How do I clean carpets, rugs, and upholstery with Koh?Updated 8 hours ago
TL;DR: For larger carpet, rug, or upholstery areas, dilute Sensitive Laundry Liquid (1 pump per 1L warm water) and run through a handheld wet-vac or carpet cleaning machine. For small spots and marks, spray Universal Cleaner lightly and blot. Avoid both products on wool and silk — the protease enzymes in Sensitive Laundry Liquid can damage protein-based fibres. Always spot test first.

How do I clean large carpet, rug, or upholstery areas?
Use diluted Sensitive Laundry Liquid with a handheld wet-vac or carpet cleaning machine. Mix 1 pump (4ml) per 1L warm water. Fill the machine tank with warm water first, then add detergent (prevents over-foaming). Run over the area following the machine's instructions, then let the surface dry completely before walking on it or replacing cushions.
✓ Dilution ratio and method
1 pump (4ml) of Sensitive Laundry Liquid per 1L warm water. Add water to the tank first, then the detergent. Use with a wet-vac or carpet machine per the manufacturer's instructions. Let the surface dry fully before use.
⚠ Avoid on wool and silk
Sensitive Laundry Liquid contains protease, an enzyme that breaks down protein-based stains (like sweat, blood, food). It can also break down protein-based fibres — wool, silk, cashmere — leading to weakening or damage over time. Not suitable for wool carpets, wool rugs, or silk upholstery.
How do I clean small spots and marks?
For small spots on carpet, rugs, or upholstery, use Universal Cleaner. Spray lightly onto the affected area (don't soak), blot gently with a clean microfibre cloth working from the outside of the stain inward, and let the surface air dry. Don't scrub. Scrubbing spreads the stain and can damage fibres. Always spot test an inconspicuous area first.
✓ Three-step spot clean
Spot test first. Spray a hidden area, blot, wait a few minutes, check for colour change before treating the visible stain.
Spray lightly, don't soak. Universal Cleaner works on contact. Over-saturating pushes the stain through the fabric and into the carpet backing or cushion foam.
Blot, don't scrub. Work from the outside of the stain inward with a clean microfibre cloth. Lift the stain, don't spread it. Air dry fully.
What about upholstery cushions and protecting the backing?
Avoid soaking upholstery cushions. Moisture can get trapped in the foam and cause mildew or odour. Keep treatment light and surface-level. For removable cushion covers, check the care label; some can be machine-washed with Sensitive Laundry Liquid (not wool/silk). For carpets, moisture reaching the backing can weaken adhesives and promote mould. Keep treatment at the fibre level only.
⚠ Don't over-saturate
Trapped moisture in cushion foam causes mildew and odour. Moisture in carpet backing weakens adhesives and can promote mould. Keep treatment light and surface-level. Results vary by fabric type, stain type, and age of the stain — always spot test first.
For large-area carpet, rug, and upholstery cleaning with a wet-vac. Dilute 1 pump per 1L warm water. Not for wool or silk.
For small spot-cleaning on carpets, rugs, and upholstery. Spray lightly, blot gently, don't soak. Always spot test first.
