Only non-chlorine (oxygen) bleach

Oxygen (non-chlorine) bleach is allowed, chlorine bleach is not. The two slanted lines inside the triangle are the whole difference from 'any bleach'.

What to do

Use oxygen-based products — sodium percarbonate stain removers, 'colour-safe' bleach, or a detergent that already contains oxygen bleach — and keep household chlorine bleach away from this item.
