Is Sensitive Laundry Liquid suitable for wool and silk?

Wool, silk and other untreated protein fibres need a cleaner formulated for them, so use a wool or silk wash on those garments instead. Koh Sensitive Laundry Liquid is formulated for cotton, polyester, nylon, elastane and blends. Always follow the garment care label, which has the final say on any item.

⚠ Wool, silk, cashmere, alpaca, mohair and angora are protein fibres, and protein fibres want a cleaner made for them. Use a wool or silk wash on those garments and follow the garment care label.

✓ What Sensitive Laundry Liquid is built for

Sensitive Laundry Liquid handles the everyday load: cotton, polyester, nylon, elastane, lycra and the blends most clothes are actually made of. Cellulase in the formula works on the tiny loose fibres that build up on cotton wash after wash, which is what helps garments keep their as-new look for longer.

What should I use for wool or silk?

Use a detergent made for protein fibres, sold as a wool wash, silk wash or delicate wash. Hand wash in cool water, or run the wool or delicate cycle, since hot water shrinks and felts wool. Lay flat to dry rather than tumble drying, and follow the garment care label.

✓ Four things that keep a knit in shape

1

Pick a wool wash, silk wash or delicate wash. Supermarkets and specialty laundry aisles both stock them. They're formulated for protein fibres, which is the whole point.

2

Keep the water cool. Hot water shrinks and felts wool, and that isn't reversible. Cool water, every time.

3

Hand wash if you can. For most wool and silk garments a cool hand wash is the gentlest route. If you'd rather use the machine, run the wool or delicate cycle.

4

Lay flat to dry. Never tumble dry a protein fibre, and don't hang a wet knit either, because the weight pulls it out of shape.

The garment care label has the final say. Where it differs from any of this, follow the label.
