To clean a leather jacket at home gather soap, a bucket, a soft rag and leather oil or conditioner. Use a very gentle soap, such as shampoo or hand wash, and warm water.
Mix the hand soap in the warm water, then dampen a rag and gently clean the outside of the jacket. Remove and wash the lining if it has zippers or snaps, or spray it with a fabric freshener if it is not removable. When the jacket is dry, coat it with a thin layer of mink oil, olive oil or leather conditioner to prevent cracking. This method keeps your jacket clean and attractive.
