Q&A for How to Wash Leather

Mix together mild dishwashing soap and warm, not hot, water. Then wipe down the leather. Avoid using vinegar because it can deepen stains in leather.

There is no way to completely remove mold growth from leather and it is recommended that you dispose of the material. If you insist on keeping the material(s), try this: For surface growth, as a result of humidity, try cleaning mold growth off the surface using a soap/detergent solution (don't need bleach). For extensive mold growth on leather, replace the affected materials if you can (cut out and patch) or clean it, dry it completely, and encapsulate it with another material. Materials that have been in contact with "grey" or "black" water (i.e. sewage) should be disposed of. Always wear proper personal protective equipment (respirator, gloves) when handling moldy materials.

Leather that has become stained, faded, or discolored may be impossible to return to its original color. Consult an expert in these situations, as you'll likely have to redye the item. Redyeing may be expensive.

You will need to apply a generous amount of Vaseline to the curry stain and rub the area with a cloth until the stain begins to disappear. Then, spray water on it (just a little or else it will leave its own stain). Apply baby powder and let it sit for around 12 hours. Use a sightly damp cloth to remove the baby powder. Do it all again if the stain is still here.
