Carpet cleaning with on-site service Almaty

Which stains cannot be removed from a carpet?

In professional on-site carpet cleaning, there is no “magic pill” — some stains remain forever, and an honest cleaning company warns about this before starting work. In our 8 years of practice in Almaty, we have developed a clear list of “unremovable” stains and inform clients when restoration is impossible, so as not to make empty promises.

Stains from aggressive dyes

Aniline dyes (ink, markers, colored drinks with synthetic pigments) penetrate the fiber structure at a molecular level — they cannot be washed out even with professional extractors. We had a case: a client spilled a bright green energy drink on a light wool carpet — after three extraction cycles with an enzyme pre-spray, a yellow-green outline remained. Black ink from gel pens on viscose carpets is also hopeless: the dye bonds with the cellulose, and attempting to remove it with a solvent destroys the thread itself. Check: if the stain does not fade after the first contact with water — it is most likely permanent.

Old oily stains

Oil, grease, and wax that have soaked into the carpet for more than a month oxidize and polymerize — turning into an insoluble film. In practice, this looks like: an oil stain from cooking grease on a synthetic carpet that is over a year old does not react to degreasers or hot water extraction. Even our hypoallergenic Kiehl chemistry with enzymes only breaks down fresh grease (up to 2-3 days old). We advise carpet owners with oil stains older than two weeks not to waste money on cleaning — it is easier to replace the section or buy a new rug. The exception is polypropylene carpets: oil does not polymerize on them and is removed with hot water at 85°C, but such models are rarely found in Almaty apartments.

Stains from improper DIY cleaning

The most common mistake Almaty residents make is trying to scrub a stain with chlorine-based products (“Belizna,” “Domestos”). Chlorine reacts with the dye, discolors the pile, and leaves a yellow stain that cannot be restored — this is not dirt, but a chemical burn of the fiber. We saw a significant New Zealand wool carpet that the owner “bleached” with chlorine — a white bald patch of 15×20 cm remained. On wool carpets, the same effect is caused by stain removers with oxygen bleach (Vanish Oxi Action): they corrode the keratin of the wool, and a hole forms at the stain site. If you have already treated a stain with unknown chemicals — tell the technician when ordering on-site carpet cleaning: sometimes 70% of the area can be saved, but not the spot itself.

Rust and metal dust stains

Rust from furniture legs, radiators, or construction rebar contains iron ions that bond firmly with the fiber. Water-based solvents and alkali only set the rust, while acidic agents (citric acid, oxalic acid) destroy the pile on wool and viscose carpets. On synthetics (polyamide, polyester), a weak acidic solution may lighten it, but the risk of a residual yellow outline is 60%. The problem is more acute in Almaty: in older housing stock (microdistricts “Almaty,” “Zhetysu”), heating pipes often leak, and rusty water drips onto carpets. The only option is to cut out and replace the damaged section, if the carpet is not a budget mass-market item.

Epoxy resin and glue stains

Construction adhesive “liquid nails,” epoxy, super glue — harden into an insoluble polymer. Solvents (acetone, white spirit) soften the resin but simultaneously dissolve the carpet dye — leaving a smear. In practice: a client was gluing baseboards with epoxy, a drop fell on a hand-made silk carpet — a profi-clean technician cut off the top layer of resin with a scalpel, but the remaining 0.3 mm high outline is still visible. The only working method is mechanical removal with a blade and subsequent masking of the pile with matching threads (if the carpet is expensive). For budget models — it is easier to buy a new one.

Old, deep-set pet urine stains

This is a separate story: the urine of cats and dogs contains urea and urochrome, which crystallize deep within the pile and backing. We remove fresh stains (up to 24 hours) with enzyme-based products at 95% effectiveness. But if more than a week has passed, the crystals penetrate the foam base, and it becomes impossible to remove them completely. In Almaty, the problem is compounded: in private homes (microdistricts “Koktobe”, “Gorny Gigant”), carpets lie on concrete floors, and urine soaks not only into the carpet but also into the screed — the smell returns within 2-3 weeks even after professional treatment. We honestly warn: for old, set-in urine stains, mobile carpet cleaning provides a temporary effect for 2-3 months, after which the carpet or its base needs replacement.

How to distinguish “unremovable” from “difficult” — a checklist for the client

• The stain does not fade upon contact with water — aniline/chemical dye, cannot be removed.
• The stain is older than 2 weeks + feels greasy to the touch — polymerization, only fresh stains can be removed.
• After bleach/whitener — chemical burn, cannot be cleaned, requires restoration.
• Rusty outline from metal — rust, cannot be removed, only masked.
• Feels hard to the touch, does not soften with water — epoxy/glue, requires mechanical removal.
• Urine smell returns after 2-3 weeks — crystals in the backing, base replacement needed.

Before ordering mobile carpet cleaning, evaluate the stain against this list. If it falls into the first four points — save your money: we will honestly say we cannot remove it. If it falls into the fifth or sixth — we will come and try, but we will only guarantee a reduction, not complete removal.

How is carpet dry cleaning different from vacuum washing?

These two cleaning methods are most often confused — but the difference between them is fundamental, like the difference between washing a shirt and ironing it. We will break down the key differences in depth of action, pile safety, and results, so you can choose what your carpet really needs.

Depth of penetration: surface dust collection vs extraction from the base

Vacuum washing collects only what lies on the surface of the pile and slightly below — sand, hair, crumbs. The water in the tank of a carpet washer washes away the top layer of dirt but does not reach the carpet’s base. profi-clean’s dry cleaning with pressure extraction washes the pile to its full depth — down to the latex base and primary backing. In our experience, up to 70% of dust particles accumulate in the lower third of the pile, which a carpet washer simply cannot wash out. If a carpet hasn’t been professionally cleaned for over a year — vacuum washing will only spread the dirt across the base, creating an illusion of cleanliness for a couple of days.

Chemistry: household foam vs professional disincrustation

Carpet washers use store-bought shampoo — it foams, leaves a sticky residue on the pile, and attracts new dust faster than before washing. We use hypoallergenic Kiehl and Sodasan formulations with enzymes that break down fat and protein molecules at the fiber level — without forming a film. The difference is visible in a white napkin test: after vacuum washing, a napkin pressed against the dried carpet leaves a yellow mark from foam residue; after our dry cleaning, it’s clean. This is crucial for allergy sufferers: residues of household chemicals in the pile trigger coughing and itching, while professional formulations leave no traces after extraction.

Result for tough stains: masking vs removal

Vacuum washing lightens coffee or juice stains but does not remove them — moisture temporarily “spreads” the pigment through the pile, and after drying, the stain returns, often with a halo. Dry cleaning with pre-treatment using an enzyme stain remover breaks down the stain’s structure into water-soluble components that are completely removed during extraction. Our technician checks every stain with a UV lamp before and after — if the stain was organic (blood, urine, juice), the UV lamp still shows fluorescence after vacuum washing, but after our cleaning — zero. For set-in red wine or grease stains, vacuum washing is useless: it only fixes the pigment in the fiber with the heat of the water.

Impact on pile structure: abrasion vs restoration

A washing machine rubs the pile with a brush and water — on wool and viscose carpets, this mats the pile, makes it look dull, and accelerates the fraying of fiber tips. Our cleaners use low-temperature extraction without mechanical friction: the solution is applied under pressure, and dirt is flushed out with a stream of water without damaging the structure. For long-pile carpets (Saxony, frieze), this is critical — after washing with a machine, the pile becomes matted and loses volume; after our cleaning, it lifts and restores its texture. Expert recommendation: if your carpet is expensive or natural — never use a washing vacuum cleaner, only professional extraction with cold water.

Drying time: wet carpet for a day vs ready in 2-4 hours

A washing vacuum cleaner leaves up to 30% moisture from the water volume in the pile — the carpet is soaked through, drying for 12-24 hours, during which mold can develop in the backing, especially during Almaty’s humid autumn. We use an extractor with a suction power of 1400 W — it removes 95% of moisture from the pile, and the carpet dries in 2-4 hours at room temperature. In our orders for carpets with latex backing, we note: if after washing with a machine the carpet doesn’t dry within a day — the latex begins to peel off, and the carpet loses its shape. For homes with children and pets, fast drying is not a convenience but a safety measure: damp pile is an ideal environment for fungus growth, which is invisible to the eye.

How often should carpets be cleaned in Almaty?

The frequency of professional carpet cleaning depends on three factors: the number of residents, the presence of pets, and proximity to the roadway. In Almaty’s reality, dust from the streets of the Medeu and Bostandyk districts settles on carpets faster than in the suburbs — here, the cycle between cleaner visits is 2–3 months shorter. Below are specific scenarios to help you avoid overpaying for unnecessary treatments and not miss the critical point for your carpet pile.

In a home without pets or children

If two adults live in the apartment and the carpet is in the bedroom or living room without balcony access, professional cleaning with a visit in Almaty is needed once every 6–8 months. During this time, up to 1.5–2 kg of dust per square meter accumulates in the microfibers — even with weekly vacuuming using a powerful HEPA-filter vacuum cleaner, fine particulate matter that rises when walking does not come out from under the pile. In our experience, clients who order carpet cleaning with a visit every six months extend the carpet’s lifespan by 3–4 years compared to those who only rely on home care. Moreover, after the rainy season in autumn, the pile accumulates more street dirt, so October is the optimal month for a scheduled service call.

If there is a pet in the apartment

For dog and cat owners, the interval is reduced to 3–4 months. Fur, dander, and saliva enzymes get stuck in the base of the pile and, when humidity exceeds 60% (typical for Almaty spring and autumn), begin to decompose — a musty smell appears that no household washing vacuum cleaner can remove. On-site dry cleaning with hypoallergenic Sodasan foam washes out biological residues to a depth of up to 10 mm, halving the risk of allergies for household members. One nuance: after treatment, pets often try to rub against the damp pile — we recommend covering the carpet with plastic wrap for 2–3 hours until completely dry.

In a zone of street dust — windows facing the avenue

Apartments with windows facing Abay, Dostyk, or Al-Farabi Avenue face increased dust levels: even with closed windows, up to 300–400 grams of black soot settles on 10 m² of carpet per month through ventilation systems. Here, the cleaning schedule is every 4 months, with mandatory hot water extraction washing in spring and autumn to flush out oily particles from exhaust fumes. We had a case: a client from a house on Sain Street postponed cleaning for 7 months, and the carpet had to be treated three times due to ingrained soot — the final cost was significantly higher than with quarterly scheduled cleaning.

Seasonal mode for country house carpets

Carpets from country houses near Almaty (Kargaly, Uzynagash) are cleaned twice a year — after winter storage and before preservation for autumn. After winter in an unheated house, mold fungus remains in the pile, invisible to the eye but giving off a specific musty smell at the first rain. Professional cleaning with on-site service is mandatory in this case before the carpet is brought into a city apartment — otherwise, fungal spores will spread to furniture and walls. Before ordering, request a moisture test from the cleaner: a safe level for storage is below 12%; if higher, dry first, then clean.

Features of cleaning carpets made from different materials

The carpet material dictates the method, temperature, and chemicals — what is safe for synthetics destroys wool, and a gentle mode for viscose is powerless against stubborn stains on polypropylene.

Wool carpets: delicacy and acid balance

Natural wool absorbs moisture like a sponge and is afraid of alkali — a regular shampoo with a pH above 8 cooks the pile, making it stiff and dull. We use only acidic compounds (pH 4.5–5.5) based on lanolin, which restore the fiber’s fatty film — after this treatment, the wool repels dirt again. Water temperature is no higher than 35 °C: hot water “sets” the pile, and the carpet loses its size. In my opinion, the main mistake owners make is trying to scrub a wool carpet with a chlorine-based stain remover; it irreversibly destroys the pigment, leaving yellow streaks that cannot be hidden even with tinting.

Viscose: finicky “artificial silk fiber”

Viscose is regenerated cellulose that loses up to 30% of its strength when wet: wet viscose cannot be scrubbed with a brush, otherwise the pile “peels off” and bald spots form. For such carpets, we use only cold water extraction cleaning (maximum 25 °C) with minimal pressure, no steam generator, and no rotating turbo brush. In October, there was a case: a client cleaned a viscose carpet with a household steam cleaner — the pile fused into a hard crust, irreparable. Before ordering cleaning for a viscose carpet, it is worth checking if it has a factory-applied water-repellent impregnation — without it, the fiber absorbs dirt instantly, and restoring the original color will require 2–3 passes.

Synthetics (polypropylene, polyester, nylon): durability and limitations

Synthetic carpets tolerate alkali, steam, and high speeds — they can be cleaned with hot water up to 60 °C with active foam, providing maximum removal of dust and grease. Nylon, unlike polypropylene, is afraid of hot drying — at temperatures above 50 °C, it deforms and loses pile elasticity. Polypropylene carpets are the most unpretentious: they do not absorb moisture, stains are removed in the first pass, but there is a nuance — oil-based contaminants (grease, cream) get clogged into the fiber structure and remain forever without an enzyme pre-spray. In our orders for synthetic carpet cleaning, the most common requests are to remove shoe marks and spilled coffee — a standard extractor handles these in one cycle, but for stubborn grease stains, pre-treatment 15 minutes before the main wash is mandatory.

Jute and sisal: natural fibers without moisture

Carpets made of jute and sisal are coarse plant fibers that rot with excess water: soaking for more than 10 minutes leads to thread breakage and mold under the backing. We clean them exclusively using the dry method — spray an absorbent powder based on corn starch, work it in with a soft-bristle brush, and collect it with a HEPA-filter vacuum cleaner. In Almaty, where humidity is high in spring and autumn, jute carpets absorb condensation even from the floor — before dry cleaning, it is worth checking the backing’s moisture level with a hygrometer: if the reading is above 60%, it is better to postpone cleaning for a dry day, otherwise the fiber will start to rot under the powder.

How to prepare a carpet for cleaning?

Preparation determines how deeply the chemicals penetrate the pile and whether stubborn stains can be removed without streaks. We will break down three key steps that profi-clean cleaners check before starting.

Dry cleaning before wet treatment

Dust and sand ground into the base of the carpet turn into an abrasive paste when wet, cutting the pile. Before wet cleaning, we always vacuum the carpet on both sides — using a powerful unit with a HEPA filter that traps 99.97% of particles down to 0.3 microns. On long-pile wool carpets, we use a turbo brush with height adjustment to avoid pulling out the fibers. Fine sand left behind by a household vacuum cleaner is removed with a vibrating attachment — it lifts 90% of hidden dirt. If this step is skipped, dark trails from residual dust will appear on the carpet after drying, requiring re-cleaning.

Dye Fastness Test

Almaty water, with a hardness of up to 7 mg-eq/L (compared to 2–3 in European cities), reacts with cheap aniline dyes, especially on handmade carpets from Iran and Turkey. Before cleaning, we always test an inconspicuous area at the edge: we apply the solution to a white napkin, press it for 30 seconds, and check for color transfer. For bright carpets with red and blue pigments, we use a pH-neutral solution with a level of 6.5–7.0 — it does not pull out the dye, unlike alkaline agents with pH 10+. If the dye is unstable, we switch to cold water (up to 25 °C) and reduce the extractor pressure to avoid bleeding. In our practice, every tenth carpet from the “Altyn Orda” bazaar shows color transfer during the test — this is normal for handmade production.

Removing Small Debris and Protecting Fringe

Coins, paperclips, plastic shards — any hard object under the pile, when the rotary machine is running, can fly out at bullet speed and tear the upholstery or injure the cleaner. We manually go over the carpet with the edge of our palm, collecting anything that clinks. The fringe on wool carpets is secured to the back with painter’s tape — otherwise, the extractor brushes twist it into a rope, and restoring even tassels is only possible with scissors. Synthetic fringe (polypropylene) just needs to be folded to the back; it won’t deform. Before departure, check the corners and seams yourself — if there are loose threads, it’s better to trim them, otherwise, during mechanical cleaning, they will stretch by a centimeter or two.
