Summarize this article:

Shake the bottle well. Squirt a small amount of white, foaming shaving cream on the stain. Gently massage the shaving cream into the stain with a clean rag or towel. Do not be too rough. Blot the shaving cream off with a clean paper towel. Do not rub, just dab it gently. Let it dry for at least 24 hours. Use a soft cloth to rub a small amount of leather conditioner into the affected area. This will help restore the leather's texture. Let it dry again.
Apply the shaving cream. Rub it in. Wipe it off. Condition the leather.
