06 More about chlorine bleach
Chlorine bleach is a powerful oxidiser and disinfectant. It destroys colour, including the colour of dyes you want to keep, and it reacts dangerously with acids, ammonia and alcohols.
On an ingredient list, chlorine bleach shows up as sodium hypochlorite (sometimes listed as "chlorine bleach" or "hypochlorite").
- It can worsen rust stains and damage incompatible fibres or dyes. It is not a universal treatment for protein stains.
Never mix it with white vinegar, ammonia, rubbing alcohol, hydrogen peroxide, oxygen bleach, lemon juice, acetone, toilet bowl cleaner, ammonia-based glass cleaner, enzyme cleaner and oxalic acid cleanser. Why.
07 Already used it?
Rinse thoroughly. If the fabric has lost stretch or gone yellow, the elastane is damaged permanently.

What should I use on leggings instead of chlorine bleach?

Can I mix chlorine bleach with other cleaners on leggings?

None of the 34 files for leggings and activewear uses it. Absence from the model does not establish either effectiveness or safety.
How long can chlorine bleach stay on leggings?
Do not use it as a routine home treatment on this material. For accidental contact, follow the product and item instructions and obtain advice if needed.
