Are there any fabrics I shouldn't use with Universal Cleaner?Updated 10 days ago

Koh Universal Cleaner is formulated for hard surfaces and synthetic-fibre textiles such as nylon, polyester and polypropylene. It is not recommended on wool, silk, cashmere, mohair, alpaca or other protein-based natural fibres. Protein fibres respond differently to cleaning chemistry than synthetics, and a higher alkaline solution can cause colour change, fibre damage, felting, shrinking or discolouration on wool or silk carpets, rugs and upholstery. Use a cleaning product formulated for delicate natural fibres instead. The same applies to wool throws, silk cushions, cashmere blankets, and any garment in those materials.

Check the care label on your carpet, rug, upholstery, or garment first, and follow the manufacturer's cleaning guidance. A specialist cleaner formulated for wool from a carpet cleaning supplier, often labelled WoolSafe approved, is the best option for regular maintenance and home spot treatment. For deeper cleans, stubborn stains, or valuable rugs, book a professional carpet cleaner who has experience with wool and silk. Rug care is one area where the cost of a professional clean is consistently lower than the cost of damaging an expensive rug. For wool throws and silk cushions, hand-wash with a wool wash following the care label, or take them to a dry cleaner.

Act fast, blot (don't rub), and use plain water only. Blotting with a clean dry Koh cloth lifts most fresh liquid before it sets. Work from the outer edge of the spill inward to avoid spreading the stain. If the spill is food, drink, or anything water-soluble, dab lightly with cool water on a clean cloth. Avoid soaking the carpet backing. Press dry with a clean towel and let the area air dry. Leave any deeper treatment to a specialist wool cleaner or a professional. The faster you act on a fresh spill, the less likely you'll need anything stronger than plain water.
