Warehouse Cleaning Almaty

How Warehouse Cleaning Differs from Office Cleaning

Many clients assume that cleaning a warehouse and an office are the same thing, but in reality, these are two different approaches: the goals, equipment, safety standards, and criteria for results all differ. Let’s break down the key differences that affect quality and cost.

Different Tasks: Cleanliness “for the Eyes” vs. Cleanliness “for Work”

In an office, cleaning is primarily aesthetic: polished floors, dust-free desks, fresh air. In a warehouse, the main goal is functional cleanliness, which ensures the safety of machinery movement and the preservation of goods. An oil stain on a concrete floor in a conference room is an aesthetic defect; the same stain in a warehouse is a slip risk for a forklift and an operator injury hazard. Dust on shelves in an office is a reason for a complaint; fine dust on boxes of food or electronics in a warehouse is a violation of storage conditions that could lead to a batch being written off. In our practice, there was a case: at a building materials warehouse, cement dust settled on the packaging of plumbing fixtures, and the buyer returned the goods — we had to repackage 60 items. Therefore, in commercial warehouse cleaning, we check not for visual shine, but for the absence of a layer of contaminants on surfaces that come into contact with the cargo.

Equipment and Chemicals — Different Load Classes

Office cleaning equipment includes vacuum cleaners with bag filters, microfiber cloths, and neutral detergents. A warehouse requires industrial equipment: floor scrubbers with polypropylene brushes or abrasive pads for concrete, HEPA-filter extraction vacuums (our fleet includes Kärcher BR 40/10 C for aisles and Nilfisk SC250 for shelves), and high-pressure washers for removing stubborn stains. The chemicals differ: for offices, hypoallergenic surfactant-based formulations (we use Kiehl); for warehouses, alkaline concentrates for oils and greases (Sodasan Industrial) and acidic ones for concrete deposits. Moreover, in food warehouses, fragrances and volatile components are prohibited: we only use certified phosphate-free products with pH-neutral final rinsing — otherwise, the smell gets absorbed into the cardboard packaging. The difference in equipment wear is significant: scrubber brushes in a warehouse are changed every 2 weeks, while in an office, they are changed every 2 months.

Sanitary Standards and Access Zones

Office cleaning involves open spaces: carpets, windows, restrooms, kitchen. A warehouse is divided into zones with different requirements: the receiving area (dust, dirt from the street), the storage area (cleanliness of shelves and aisles), and the shipping area (oils, packaging residue). Warehouses storing food products operate under the HACCP standard — the cleaner must work in disposable clothing, gloves, and shoe covers, and equipment is color-coded (blue for floors, green for shelves). In an office, changeable shoes and general equipment are sufficient. Another difference is the cleaning time: in an office, it’s done after 6:00 PM when employees have left; in a warehouse, which often operates in two shifts, cleaning is scheduled “between shipments” — for example, from 2:00 PM to 4:00 PM when forklifts are charging. We coordinate an access map with the client: which aisles to block, where to place temporary barriers so that cleaning doesn’t halt shipping.

Acceptance Criteria: What is Considered “Clean”

Office acceptance is a subjective assessment: “comfortable to be in, no dust on the desk, windows are clear.” In a warehouse, it involves objective, measurable parameters: no slippery film on the floor (checked by friction coefficient), residual dust level on shelves (test plate), absence of foreign odors in the storage area. For warehouses with high racks (6–8 meters), we use vacuum cleaner extensions and telescopic mops — a standard office mop can’t reach the top shelves. In the contract with the client, we specify a checklist of 15 items, from “no oil marks on the floor” to “cleanliness of ventilation grilles.” This reduces disputes during acceptance; for example, at one auto parts warehouse, the client demanded a “perfectly dry floor,” but after our anti-slip treatment, the floor remained damp for 40 minutes — we had to agree on a ventilation time and include it in the checklist. Without such a document, every cleaning turns into a negotiation.

Typical Mistakes When Ordering Non-Specialized Cleaning

The most common mistake is trying to save money by hiring office cleaners for a warehouse. The result: within a month, the floor becomes covered in an oily film that standard chemicals can’t handle, and streaks remain on the shelving from unsuitable cleaning agents. The second mistake is ignoring seasonality: in winter, there’s more dirt from forklift wheels (de-icing agents, sand) in the warehouse, and in summer, more dust from open doors. An office cleaner doesn’t track these cycles, but we adjust the chemical composition and frequency of wet cleaning according to the season. The third is improper drying: in warehouses with concrete floors, moisture remains after washing, which doesn’t evaporate when pallets are loaded and causes mold in the lower layers of packaging. We use a “drying + finish coating” mode for all warehouses with concrete — this extends the floor’s service life and protects the goods. If you order warehouse cleaning from a company without industrial experience, these nuances won’t be considered, and in six months, you’ll need a major floor wash involving dismantling the shelving.

Features of Cleaning Cold Storage Warehouses

Cold storage warehouses are a separate category of facilities: low temperatures, high humidity, specific contaminants, and strict sanitary standards for food products. profi-clean cleans such premises considering all risks and regulations, so I’ll outline the main differences and pitfalls.

Why Regular Cleaning Isn’t Suitable for Cold Rooms

In my opinion, the main mistake a client makes is trying to hire universal cleaners who wash offices. In a cold storage warehouse at −18…−25 °C, regular water freezes within 5–7 minutes, and standard water-based cleaning agents turn into an icy crust. We use specialized Kiehl concentrates with a low freezing point (down to −30 °C) — they don’t crystallize and effectively remove fatty and protein deposits typical for meat and dairy warehouses. Additionally, at sub-zero temperatures, the chemical reaction slows down by 2–3 times, so the product’s dwell time increases from 3 to 8–10 minutes. Without considering this factor, deposits remain on surfaces. In our practice, there was a case where a client lost a batch of cheese because a cleaner spilled warm water — the condensation froze on the packaging, compromising its seal. Before cleaning a cold storage warehouse, request a certificate for the cleaning agents from the contractor indicating the working temperature — this is the only way to guarantee the chemicals will work and not freeze.

How Humidity and Condensation Affect Product Safety

In cold rooms, humidity stays at 75–95%, and when doors are opened, warm air instantly condenses on walls and ceilings. This moisture is an ideal environment for mold (Aspergillus, Penicillium) and bacteria (Listeria, Pseudomonas), especially in sandwich panel joints and behind shelving. profi-clean uses wheeled air dehumidifiers (capacity from 200 m³/h) — they reduce humidity to 50–60% within 30–40 minutes before cleaning begins, preventing condensation during washing. Without dehumidification, water drips from the ceiling onto goods, and an oily film forms on the floor — this is a direct risk of slipping and product spoilage. In Almaty warehouses on Yemtsova Street, we recorded wall moisture levels 15–20% above normal due to frequent door openings in summer — we had to change the cleaning schedule to nighttime when loading is minimal. If your warehouse stores products without airtight packaging (vegetables, greens, baked goods), insist on air dehumidification before any wet cleaning — otherwise, condensation will spoil the goods faster than dirt.

Mistakes in Choosing Equipment for Sub-Zero Temperatures

At −20 °C, plastic buckets and mops become brittle — they crack on impact, and rubber squeegees stiffen and stop collecting water. We have switched to polypropylene buckets with a wall thickness of 3 mm (standard ones are 1.5–2 mm) and silicone squeegees with frost resistance down to −40 °C. Another typical mistake is using synthetic microfiber cloths: at sub-zero temperatures, they freeze, the pile breaks off and leaves lint on products. The solution is cotton rags with a density of 400 g/m², which remain elastic down to −25 °C. An important nuance: after cleaning, all equipment is washed in warm water (not above +40 °C) and dried in a ventilated room — if you leave wet rags in the cold, they will freeze solid like a board and tear during the next use. In warehouses in Almaty with year-round sub-zero temperatures (for example, at a wholesale base in the Kulager microdistrict), we maintain a separate set of tools that is never brought into the warmth — temperature changes reduce the service life of plastic by three times. Get a separate set of equipment for cold storage rooms and store it at the warehouse’s operating temperature — this way you won’t waste time thawing it out and won’t risk breakages.

How the drainage system differs from regular washing

When washing a cold storage warehouse, water does not evaporate — it remains on the floor and freezes if not removed within 10–15 minutes. In regular warehouses, it is enough to wipe the floor with a mop, but here mechanical water collection is required, followed by removal through drains or industrial water vacuums. profi-clean uses Nilfisk floor scrubbers with a vacuum liquid collection function — they collect up to 95% of the water in one pass, leaving the surface dry. Without this, water flows under pallets with products, freezes to the pallets, and when moving goods, pieces of ice tear off along with the packaging. At a fruit warehouse in Almaty (Tastak-2 district), we observed how a 2–3 mm layer of ice under pallets blocked ventilation — the temperature in the zone rose by +4 °C in a day. After washing, be sure to check the drain traps for blockages — in cold rooms, they often get clogged with grease and pieces of packaging, and without cleaning, the water does not drain but spreads across the entire floor. Plan the cleaning of the cold storage warehouse for a period when product movement is minimal (usually 22:00–06:00) — then the water will have time to be collected and drained before the start of the work shift.

Cleaning specifics for different product types

The category of stored products dictates its own cleaning rules. In meat warehouses (carcasses, semi-finished products), grease contamination predominates — it needs to be removed with alkaline agents with a pH of 11–12, but only after the complete removal of products to avoid chemical burns to the packaging. In fruit and vegetable warehouses, the main problem is ethylene released by the fruits: it settles on the walls as a sticky coating that attracts dust and mold spores. Here we use neutral detergents Sodasan with added enzymes — they break down organic matter without aggressive chemicals. Dairy warehouses require disinfection after each cleaning, as milk protein is an ideal breeding ground for bacteria: 1 gram of residue per 1 m² of surface gives a 10-fold increase in microorganisms in 4 hours at +4 °C. In Almaty, there is a frozen semi-finished products warehouse (Zhandosov St.) where we divided cleaning zones: red equipment for the meat zone, blue for the dairy zone, green for the vegetable zone, to eliminate cross-contamination. Before ordering cleaning for a cold storage warehouse, check with the cleaning company whether they have protocols for your type of product — a universal approach here is dangerous for the quality and shelf life of goods.

What disinfection products we use in warehouses

In warehouses, disinfection is not about floor shine, but about destroying pathogenic flora that multiplies in dust, on shelves, and in the goods receiving area. At profi-clean, we use a three-level system: alcohol-based, oxygen-based, and quaternary ammonium compounds — each for its own type of surface and contamination.

Why regular household chemicals don’t work in a warehouse

Household products with chlorine or alkali are designed for short-term contact of 5–10 minutes and low bacterial load. A warehouse with heavy equipment and personnel traffic requires professional concentrates with an exposure time of 15 to 30 minutes — otherwise, mold spores and staphylococcus survive. In practice, we have encountered clients who tried to wash shelving with bleach: within a month, black mold reappeared in the corners because chlorine evaporates faster than it penetrates the micropores of concrete. In our work, we use oxygen-based compounds with hydrogen peroxide — they have no strong odor, leave no white residue on metal shelving, and work at temperatures from +2 °C, which is critical for unheated warehouses in Almaty. Moreover, for high-humidity areas — such as near gates or in cold rooms — we choose QAC products with prolonged action: they remain active on surfaces for up to 24 hours and suppress mold growth between cleanings.

How do products for floors and shelving differ

The warehouse floor is concrete with micro-cracks and oil stains, while shelving is painted metal and plastic — each requires its own formulation. For concrete floors, we use alkaline concentrates with a pH of 11–12, which break down oils and rubber crumbs from forklift wheels — after mechanized washing, the floor becomes matte and slip-resistant. For shelving, conversely, we use neutral alcohol-based solutions with a pH of 6–7 to avoid damaging the coating and leaving streaks on product packaging. In our orders for building materials warehouses in Almaty, a common mistake was cleaners applying the same compound to both floors and shelving — after six months, the paint on metal shelves would start to bubble. Our protocol mandates separate containers and color-coded cloths — blue for floors, green for shelving — to prevent cross-contamination.

What safety certificates do we check before purchasing

Every product that enters our chemical warehouse undergoes a triple check: a certificate of conformity to TR CU 009/ for safety, an MSDS safety data sheet specifying the composition and hazard class, and a compatibility test with the client’s materials. For example, for warehouses storing food products — flour, grains, spices — we use only phosphate-free and chlorine-free products that leave no odor and do not migrate into packaging. In our practice at a warehouse in Almaty, a client asked us to confirm that the disinfectant does not react with the polypropylene film on pallets — we provided an excerpt from the MSDS and a test report on a sample. Certificates for Kiehl and Sodasan are kept in open access for any client: they confirm that the concentrates are 98% biodegradable and do not accumulate in wastewater.

How often should a warehouse be deep cleaned

The frequency of warehouse deep cleaning is not a fixed number but a derivative of the type of stored goods, equipment traffic intensity, and regulatory requirements. In Almaty, this is compounded by seasonal factors: dust storms in spring and sticky mud after autumn rains. Below, we break down scenarios where the frequency changes and mistakes that turn prevention into emergency restoration.

For warehouses of dry building materials and packaging

In warehouses of cement, gypsum, sand, and cardboard packaging, we at profi-clean perform deep cleaning once every 1–2 months, but with mandatory intermediate dust removal once a week. Building material dust is abrasive: it clogs forklift bearings, settles on drive belts, and reduces equipment lifespan by 30–40% compared to a clean warehouse. Cardboard dust, in turn, is a combustible suspension: in an enclosed space with sparking equipment, the concentration can reach the lower explosive limit. Practical advice: during deep cleaning of such warehouses, be sure to blow out the supply ventilation ducts — accumulated dust there, when the system starts, raises a cloud that settles on freshly washed shelving within an hour.

For food and refrigerated warehouses

At facilities with food products, especially in refrigerated chambers, general cleaning is mandatory once a month — this is a requirement of the technical regulation TR CU 021/, not our recommendation. In summer, when the temperature in Almaty reaches +35°C outdoors, humidity in non-hermetic chambers increases, and mold appears at panel joints within three weeks. In our orders, there was a case: at a vegetable warehouse, general cleaning was postponed for two months, and mold penetrated the control panels of refrigeration units — we had to replace contactors at a cost exceeding the annual cleaning price. At food warehouses, we additionally treat drainage trays and evaporators — condensate accumulates there, becoming a breeding ground for legionella. Due to this fact, we reduce the interval between general cleanings in the warm season to 21 days, rather than 30.

For warehouses with light industry and consumer goods

Clothing, footwear, textiles, household chemicals — goods that absorb odors and dust through packaging. At such warehouses, general cleaning once a quarter is the lower limit, but with high turnover (more than 50% of goods per month), we recommend once every 2 months. Dust in textile warehouses is not just dirt: it contains microparticles of dyes and finishing compounds that migrate through the micropores of polyethylene packaging within 3–4 weeks of storage. In Almaty, where the air is drier than in coastal cities, the electrostatic charge on packaging retains dust 2–3 times longer. During general cleaning of such facilities, we necessarily wash not only floors and racks but also ceiling beams — up to 15% of all dust in the room settles on them, and when ventilation operates, it is evenly distributed over the goods. Our experience shows: if only the lower zone is washed, a month after cleaning, dust on the upper shelves returns to its original level.

For warehouses with chemical reagents and flammable liquids

Here, the frequency of general cleaning is dictated by substance safety data sheets, not the calendar. For most bulk reagents (caustic soda, nitrates, phosphates) — once every 2 weeks, for liquid flammable liquids — weekly wet cleaning of floors with a neutralizing solution. Missing even one cleaning at an ammonium nitrate warehouse leads to the formation of a crust on the floor: under mechanical impact (forklift traffic), the crust crushes into a fine dust that enters the air and causes irritation of the mucous membranes in personnel. At profi-clean, at such facilities, we use pH-neutral compounds and check the acidity of rinses with test strips — this is a mandatory acceptance stage. At flammable liquid warehouses in Almaty (most are in industrial zones behind CHP-2), we additionally wash walls to a height of 1.5 meters: when solvents evaporate, a sticky coating forms on them, which collects dust and becomes flammable. Advice: if general cleaning at your warehouse coincides with the receipt of a large batch, reschedule it to a day with minimal movement — a wet floor with residual cleaning agent and equipment traffic create an abrasive suspension that wears out the floor coating 2 times faster than normal operation.

Why you should order warehouse cleaning from profi-clean

Choosing a cleaning service for a warehouse is a decision that affects not just cleanliness, but product safety, personnel safety, and passing inspections. At profi-clean, we encounter the consequences of poor cleaning every day: from a clogged ventilation system to a spoiled batch of products. Let’s break down what to really pay attention to when choosing a contractor, and why a direct performer is more profitable than a “one-hour” crew.

Risks when working with unprofessional crews

Savings on warehouse cleaning is a common mistake that leads to direct losses. In Almaty warehouse complexes, we have seen the consequences of untrained crews: washing floors with plain water and household detergent leaves a greasy film that accumulates dust and becomes slippery — increasing the risk of injury. After such “cleaning,” racks have streaks and drips, and concrete floors develop a white residue from improperly selected chemicals that seeps into the pores and cannot be removed without grinding. Another risk is using cheap chlorine-based household chemicals: in warehouses with food products or pharmaceuticals, chlorine fumes are absorbed into cardboard packaging, which can lead to the rejection of an entire batch during a SES inspection. At profi-clean, we work only with hypoallergenic concentrates from Kiehl and Sodasan — they leave no odor and are chemically neutral for packaging materials. In practice, this means that after our cleaning, new goods can be immediately placed in the warehouse without airing out or additional sanitary treatment.

Why a Direct Contractor is More Reliable Than a Crew Through an Aggregator

The difference between a direct cleaning service and a crew from an aggregator is not in price, but in accountability for the result. Aggregators act as intermediaries: they take an order, pass it to a random crew, and when a complaint arises, they shrug it off — “that’s not our employee.” At profi-clean, we have in-house cleaners who have been trained in warehouse protocols: they know how to wash racks without shifting cargo, what humidity level is acceptable for dry bulk product warehouses, and how to treat loading and unloading areas without stopping operations. In October, we had a case: at a building materials warehouse, a cleaner noticed a roof leak above pallets of drywall — he stopped work, moved the pallets, and called a repairman, preventing damage to goods worth 1.2 million tenge. An aggregator crew would have simply mopped the floors and left — the problem would have been discovered a week later when the drywall was already soaked. When ordering through a direct service, you get a 24-hour guarantee: if something goes wrong, we return and redo it for free, without arguments or correspondence with tech support.

Chemical Safety for Warehouse Goods — What Really Matters

The choice of cleaning agents for a warehouse is not about shine, but about preserving the product. Most cheap cleaning companies in Almaty use universal alkaline concentrates — they are cheap and effectively wash away grease, but leave an alkaline film on surfaces that destroys polyethylene packaging and corrodes metal racks. In warehouses with electronics or paper products, alkali can damage contacts and soften cardboard. At profi-clean, we use only certified Kiehl and Sodasan products — all have a neutral pH (5.5–7.5) and a biodegradable composition, meaning they are safe even with direct contact with packaging. In food product warehouses, we additionally use products with HACCP certification — they do not require rinsing after disinfection and leave no residue. Moreover, even in warehouses for building materials and auto parts, we do not use aggressive chemicals: we remove oil stains from concrete with special enzyme compounds that break down petroleum products without an acidic reaction — this extends the service life of the concrete floor by 3–5 years compared to acid washing.

Equipment with HEPA Filtration — Not Marketing, But a Necessity

Industrial vacuum cleaners with HEPA filtration are a mandatory requirement for warehouse cleaning, but not all cleaning companies comply with it. Cheap crews use ordinary construction vacuum cleaners without fine filters: they stir up fine dust (cement, flour, rubber) into the air, which settles on racks and goods 15–20 minutes after cleaning. In warehouses with electronics or pharmaceuticals, such dust is a direct risk of defects. At profi-clean, all floor scrubbers and vacuum cleaners are equipped with H13 class HEPA filters, which trap 99.97% of particles up to 0.3 microns in size. This is critical for Almaty warehouses during the dusty season (March–October), when sandy suspension from the street enters through the gates and settles on goods. We also use floor scrubbers with a vacuum drying function — after them, the floor is completely dry within 2–3 minutes, eliminating slipping and allowing forklift traffic to resume immediately. In practice, this saves 30–40 minutes of warehouse working time per shift compared to mopping with a mop and subsequent drying.

Why Almaty Warehouses Need a Local Contractor

The specifics of Almaty warehouses include high air humidity (especially in foothill areas — Medeu, Bostandyk) and sharp temperature fluctuations between storage zones. Humidity of 60–75% during the warm season creates an ideal environment for mold on shelving, particularly in cardboard packaging storage areas. Warehouse cleaning in Almaty requires selecting chemicals and cleaning schedules tailored to specific climatic conditions: for example, during periods of high humidity, we reduce the interval between wet and dry cleaning to 30 minutes to prevent water stagnation on the floor. Additionally, the city operates various types of warehouses — from cold storage chambers to open construction material sites — and there is no universal cleaning protocol. profi-clean has been operating in the Almaty market for 9 years and knows the specifics of each district: in warehouses on Ryskulova — increased dustiness due to proximity to the industrial zone, in Zhetysu — frequent issues with roof leaks, in the Alatau district — sand drifts from construction sites. A local contractor, unlike a team from the suburbs, arrives at the site within 60 minutes, knows the roads, and is not delayed by traffic jams — which is critical for warehouses operating around the clock.
