The next symbol on the care label is a triangle that refers to whether specific bleaching conditions can be used on the item
Bleach: A triangle without anything in the middle means that any kind of bleach can be used on the clothing when needed.
Non-chlorine Bleach Only: A triangle filled with diagonal lines means that only non-chlorine bleaches should be used. Check the ingredients on your bleach to see if it contains chlorine.
Do Not Bleach: A solid black triangle with crossed lines means ‘do not bleach’ – you should not attempt to use any kind of bleach on this garment.
