Tufted carpet tiles are cleaned differently from ordinary carpet. Using the wrong equipment, detergent, or wet-cleaning method causes yarn damage, detergent residue, and mould — and ultimately cuts the carpet's service life in half.
Cleaning method by stain type and area
Daily maintenance
Abrasive dust · prevents permanent damage
Water-based stains (tea, coffee, wine)
Treat before drying — top priority
Periodic deep clean (every 3-6 months)
Residue test → 1:64 dilution → Defoamer 1:100 → 24h dry
Cleaning during business hours
Entryways · corridors · partial areas
Daily Vacuuming
Daily cleaning with a carpet-specific vacuum removes abrasive dust particles that wear down carpet fibres, preventing permanent damage.
We recommend an upright dual-motor vacuum cleaner. The suction motor and the carpet-brushing motor must operate independently so that the rotating brush can dislodge deep-pile dust while simultaneously lifting compacted yarns. Set the brush height so it makes contact with the pile surface.
A standard single-motor commercial vacuum removes only surface debris and cannot extract dirt embedded deep in the pile. Vacuum bags must be emptied regularly; ensure all cleaning staff are aware of this.
Spot Cleaning
Most stains are water-based (tea, coffee, carbonated drinks, wine, etc.) and can be removed effectively with a carpet-specific cleaner such as Ecolab Revitalize Miracle Spotter. Follow the steps below.
- Act immediately before the substance dries — blot up as much liquid as possible with a dry cloth.
- Remove the bulk of viscous spills (sauces, etc.) with a spoon or spatula.
- Press an absorbent paper towel or cloth firmly onto the stain — do not rub.
- Once no more liquid transfers, apply a carpet-specific cleaner, agitate gently with a brush, and blot dry with a clean cloth.
- For fully dried stains, apply cleaner and allow approximately 30 seconds of dwell time before treating in the same way.
Full-Room Cleaning — Wet Method
Tornex carpet tiles — like most tufted carpet tiles — must not be cleaned with a spin bonnet (rotary bonnet) machine. Spin bonnets are designed for hard floors. The horizontally rotating pad damages carpet fibres and cannot extract dirt from deep within the pile.
Bonnet machines also generate excessive detergent and foam, leaving residue that attracts airborne dust and accelerates re-soiling, ultimately causing permanent distortion and damage.
Spin bonnet is for hard floors, not carpet tile. Using one risks voiding the warranty.
Step 1 — Test for Detergent Residue
If existing detergent residue is present in the carpet, cleaning can proceed without additional detergent. Spray warm water onto the carpet and scrape the surface; heavy foaming indicates significant residue. In that case, skip Step 2 and proceed directly to Step 3.
Step 2 — Apply Detergent
Dilute Ecolab Revitalize Liquid Extraction Carpet Cleaner at a 1:64 ratio with water and spray onto the carpet tiles under pressure. Allow approximately 10 minutes of dwell time (do not leave longer or the detergent will dry). Strict adherence to the dilution ratio is essential — excessive application leaves residue that causes re-soiling.
Step 3 — Extraction (hot water not exceeding 50 °C)
Fill the clean-water tank of the wet vacuum extractor with hot water not exceeding 50 °C and add Ecolab Revitalize Defoamer at a 1:100 ratio (Defoamer reduces foam generated during cleaning, protecting the machine). Empty the recovery tank when full, refill with fresh hot water, and continue cleaning.
Step 4 — Allow Full 24-Hour Drying
Carpet tiles must dry for up to 24 hours; do not walk on them until completely dry. Drying time can be improved with air conditioning, air movers, or warm-air blowers.
The 24-48h window after wet cleaning is the mold growth threshold. Do not walk before fully dry.
Full-Room Cleaning — Dry Method (Dry Compound)
Dry cleaning with compound powder causes minimal carpet wear and is the most favourable method for carpet longevity — the manufacturer's preferred approach. It allows spot-cleaning of high-traffic areas such as entrances, corridors, and aisles; generates little noise; and permits immediate foot traffic after cleaning, so work can continue uninterrupted.
Recommended Vacuum Cleaner Spec Comparison
Tornex has compiled the specifications of four recommended carpet tile cleaning machines — compact vacuum, mid-size vacuum, dryer, and mid-size wet extractor — in a single table. Select the appropriate equipment for each site based on coverage area, working width, and suction pressure.

Summary — Five Principles of Carpet Care
- Use dust-control mats (exterior and interior) to reduce carpet tile cleaning frequency.
- Maintain daily cleaning with an upright dual-motor vacuum.
- Treat stains immediately before they dry — time is directly proportional to removal difficulty.
- Hot-water wet extraction deep cleaning: every 3–6 months at 1:64 dilution, with full 24-hour drying.
- Never use spin bonnet or rotary machines, and ensure no detergent residue is left behind.
