Body oil from hands, hair or any other body part that comes into contact with a leather chair can stain the leather. The body oil builds up on the leather surface, and you cannot remove it with soap and water. To clean body oil from a leather chair, you must use a leather cleaner and degreaser. These products have a pH that will not harm the leather, but are strong enough to break down the body oil.
Dampen a microfiber cloth with 2 tbsp of leather cleaner and degreaser. Rub the cleaner into the soiled area for 30 seconds. If the soiled area is larger than 12 square inches, rub the cleaner into each 12-square-inch area for 30 seconds.
Leave the cleanser and degreaser on the leather for two minutes.
Dampen a terry cloth towel with water and wipe down the surface of the leather chair to remove the cleanser. After each wipe, move to a clean spot on the towel so you don't spread the cleanser around.
Repeat the process if the towel continually comes up soiled when you are rinsing the leather chair.
