Master Cabinetmaker’s Ink & Lipstick Remover is water-based and made to remove ink and lipstick stains from “smooth” types of leather. Apply the product directly onto the stain so that it dissolves, and then remove it with a soft cloth. After the product is used, the leather should be treated with Master Cabinetmaker’s Leather Cleaner and Master Cabinetmaker’s Leather Conditioner.
