Can I use Sensitive Laundry Sheets on wool?Updated 8 days 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 are different

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.
