Chlorine bleach
Sodium hypochlorite solution, usually 3–8% as sold. A strong oxidiser and disinfectant. pH 11–13.
Never mix with vinegar, other acids, ammonia, rubbing alcohol or hydrogen peroxide: these release toxic gases or react violently.

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?
Wipe it off with a damp cloth straight away, let the leather dry naturally, then condition it. A dull, pale or sticky patch means the finish has been stripped and needs a leather recolouring balm or a professional.

No. Dilution slows the damage but does not change what chlorine bleach does to leather: it burns the dye and finish off leather.
What should I use on leather instead of chlorine bleach?
Use the method in the stain file for the specific stain: on leather the right product depends more on the stain than on habit.
Can I mix chlorine bleach with other cleaners on leather?
Do not combine cleaners unless the exact product manufacturers explicitly direct that use. This ingredient-level file cannot establish compatibility of commercial formulas. Rinsing alone does not prove that later use of a different cleaner is safe, especially on porous materials.

None of the 41 files for leather uses it. Absence from the model does not establish either effectiveness or safety.
How long can chlorine bleach stay on leather?
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.
