Can I use Sensitive Laundry Sheets on wool or silk?Updated 2 hours ago
TL;DR: Sensitive Laundry Sheets are not recommended for wool, silk, cashmere, or other protein fibres. The formula includes protease, an enzyme that can weaken these fibres over time. Use a wool-safe, enzyme-free detergent instead.

Why wool and silk need different care
⚠ Not recommended for protein fibres
Wool and similar fabrics are protein fibres made of keratin. Sensitive Laundry Sheets contain protease, an enzyme that targets protein stains like blood and sweat. With repeated use, protease can also act on the fibre itself, weakening wool over time. The rest of the cleaning ingredients are fine for most fabrics, but the enzyme blend makes the product unsuitable for wool.
✓ What to use instead
Choose a wool-safe, enzyme-free detergent. Wash cold or cool on a gentle cycle or handwash. Use a mesh laundry bag, select low spin, and dry flat away from heat.
⚠ Other fibres to treat like wool
✓ Avoid Sensitive Laundry Sheets on cashmere, alpaca, and mohair
✓ Silk and silk blends count as protein fibres and should also be avoided
✓ For anything unfamiliar, spot-test on an inside seam before washing
What if I used a sheet by mistake?
⚠ What to do
Rinse the garment well in cool water.
Rewash with a wool-safe detergent on a gentle cycle.
Avoid heat until the fabric looks and feels normal.
