Our 7-Step Carpet Cleaning Process

Every clean begins with an assessment of what we are working with. This is not a formality , it is the step that determines every subsequent decision. Our technician walks the area systematically, identifying the carpet or upholstery fibre type (nylon, polyester, polypropylene, wool, cotton, blended), construction method (cut pile, loop pile, Berber, frieze, woven), pile density, and backing type.

Simultaneously, we identify pre-existing damage: sun bleaching, chemical discolouration, oxidation stains, fibre wear, and previous cleaning residue. These are documented and discussed with the client before any chemistry is applied. If a stain falls into a category we cannot remove , sun damage, bleach discolouration, physical fibre wear , we say so clearly at this stage. We will not charge a client for a result we cannot achieve.

The assessment also identifies any areas of concern: delicate antique rugs, manufacturer care labels on upholstery, high-moisture-risk areas (concrete subfloors, poorly ventilated rooms), and any previous chemical treatments the client has applied that might interact with our pre-spray. This information shapes the entire clean.

Pre-vacuuming is the step most commonly skipped by budget operators , and the omission is expensive. Dry particulate soil , skin cells, sand, pet dander, food particles, dust mite debris , sits within the carpet pile before any moisture is introduced. If this dry soil is not removed before wet extraction, it mixes with the cleaning solution under the wand and forms a slurry that the extraction equipment struggles to remove cleanly.

The result is a carpet that looks clean when wet but dries with embedded residue , soil that wicks back to the surface as the moisture evaporates. This is one of the primary causes of rapid re-soiling after cleaning: not the carpet, not the chemistry, but skipping this step.

We use commercial-grade HEPA-filtered vacuum equipment for pre-vacuuming, working methodically with overlapping passes in both directions across heavily soiled areas. Corner tools and crevice attachments address skirting boards and furniture edges where dry soil accumulates. The result is a carpet that responds to wet chemistry with dramatically less interference from residual dry particulate.

Pre-spray is a surfactant solution applied to the carpet pile before agitation and extraction. Its function is to break the chemical bond between soil particles and carpet fibre, bringing embedded soil into suspension so the extraction step can remove it efficiently. Pre-spray chemistry must be matched to the fibre type: alkaline pre-sprays (higher pH) are appropriate for synthetic fibres like nylon and polyester, while wool, silk, and natural-fibre carpets require pH-neutral or mildly acidic chemistry to prevent fibre damage and dye bleed.

Applying the wrong pH chemistry to wool or a natural-fibre rug is one of the most common causes of damage in the industry. An alkaline pre-spray on a wool rug causes the fibre scales to open , the same process as felting wool in a washing machine , producing irreversible texture damage and potential shrinkage. This is precisely why the fibre assessment in Step 1 is non-negotiable: it determines which chemistry is applied here.

We allow the pre-spray a dwell time of 5 to 10 minutes depending on soil load. During this time the surfactant is actively working to loosen soil from the fibre. Rushing past this dwell time reduces the effectiveness of extraction significantly.

After the pre-spray has dwelled, agitation works the surfactant into the pile so that loosened soil reaches the extraction zone. The method of agitation varies by fibre type and pile construction: cut pile carpet can tolerate a rotary brush or grooming rake, while delicate wool loop-pile and frieze carpet requires manual agitation with a soft grooming tool to avoid pile distortion.

Over-agitation is a common mistake , particularly on older carpets where fibre integrity is reduced. Excessive rotary agitation on frieze or long-pile carpet can cause pile twist deformation that is permanent. Our technicians are trained to calibrate agitation intensity to the specific carpet underfoot, using the assessment from Step 1 to guide the decision.

Agitation on upholstery is performed with a soft upholstery brush working in the direction of the fabric weave. Pile fabrics like velvet are agitated by hand in a single consistent direction to avoid crush marks. This step ensures that by the time the extraction wand arrives, the chemistry has done the preparatory work and the extraction pass removes rather than merely redistributes.

Water extraction is the core of the clean. Our machine injects a precise volume of water and cleaning solution into the carpet pile under pressure, then immediately vacuums the solution back out along with the loosened soil and dislodged chemistry. We use normal-temperature water rather than heated water , the chemistry and mechanical action do the work, and avoiding heat keeps wool, silk, natural-fibre rugs, and dyed carpets safe from the shrinkage, felting, and dye bleed that heat can cause.

Extraction stroke technique affects the result significantly. We work in overlapping forward-and-back passes, with each recovery stroke removing the solution injected in the preceding forward pass. Correct overlap prevents "striping" , visible lines of cleaner and dirtier pile that result from insufficient coverage. The number of passes varies with soil load: heavily contaminated traffic areas may require three or four passes before the recovery solution runs clear.

Water quantity management , the volume of solution injected relative to pile density , determines drying time. Over-wetting saturates the carpet backing and subfloor, dramatically extending drying time and creating conditions for mould growth in the backing. Our technicians calibrate injection volume to pile density and backing type, never introducing more moisture than the extraction step can efficiently recover.

After extraction, stubborn stains that have not fully responded to the pre-spray and extraction pass are targeted individually. Stain treatment uses chemistry matched to the stain type , oxidising agents for organic pigments (wine, blood, coffee), reducing agents for certain synthetic dyes, enzyme treatments for protein-based stains (pet urine, vomit, food), and solvent spotters for oil-based contamination (grease, lipstick, some ink).

Pet urine treatment is a specific protocol that goes beyond deodourising. Urine crystallises in carpet fibre and backing over time, and the crystals reactivate with humidity , producing the characteristic odour on damp days even after surface cleaning. Our urine treatment uses enzyme-based chemistry that breaks down the uric acid crystals at the source, not merely masking the odour. Areas with severe urine saturation that has reached the subfloor or tack strips may require supplementary treatment , we advise on this honestly during the assessment.

Deodourisation is applied as a fine mist after extraction to neutralise residual organic odours in the pile. Rejuvenation treatment is applied to restore suppleness and static resistance to synthetic fibre after cleaning. Hypoallergenic treatment , a finishing rinse that removes allergen proteins (dust mite faeces, pet dander, pollen) from the pile , is applied as the final chemistry step.

After extraction and treatment, the carpet pile is groomed with a carpet rake or grooming brush. This serves two purposes: it opens the pile to air flow, accelerating drying time, and it aligns the pile in a consistent direction, which improves the visual finish significantly. On cut pile carpet, correct grooming produces a clean, uniform appearance. On frieze or textured pile, grooming prevents clumping as the carpet dries.

Drying time is one of the most visible measures of a quality clean. Carpets that take 24 hours or more to dry typically indicate over-wetting , too much solution applied and insufficient recovery. Our target is 2 to 6 hours for most residential carpets under typical Gauteng conditions. Humidity, ventilation, pile density, and backing type all influence this: a wool rug on a concrete subfloor in winter with poor ventilation will take longer than a thin polypropylene carpet in a well-ventilated room.

We advise clients to ventilate the cleaned area , open windows and internal doors , and to avoid walking on the carpet until it is at least 80% dry to prevent redeposition of soil from foot traffic. We place drying markers at the room entrance and provide a follow-up call for any concerns about drying progress.

The clean is only complete when the carpet is dry, the pile is groomed, and any furniture protection tabs are in place. We do not leave until this is confirmed.
