Human: I'd like to know the best way to clean a leather jacket. Assistant: 
The best way to clean a leather jacket is by using a soft, damp cloth and some saddle soap or leather cleaner. Make sure to test on an inconspicuous area first to make sure it won't damage the material. Then, gently scrub with the damp cloth in circular motions, working from the outside towards the center of the jacket. Finally, rinse off any excess soap with water and dry the jacket completely before wearing it again.
