How to clean mouldy leather ?

Thanks , I like the advice. i guess there are lots of dry cleaners in Doha.

shoe polish for cleaning, almost similar, use shoe lether deodorant also will help, I have one too

Here is what you can try:

Dry out the jacket in warm room temperature until completely dry.

Remove surface mould with a damp cloth. If leather is dry, mould will wipe off.

Allow the jacket to dry a second time.

Clean dried jacket with a leather cleaner or a very mild shampoo such as baby shampoo.

Keep the jacket properly stored to in dry area to prevent the mould from returning.

Never use a detergent.

Do a spot test and allow it to dry before cleaning the entire jacket.

If the home method does not work, contact a "professional" dry cleaner.
