Hi-Tech Magna MARK Professional Ink Remover works great on most automotive interior surfaces such as headliners, visors, leather upholstery with top coat, cloth upholstery, plastic and vinyl surfaces.
Simply rub the ink mark back and forth with the pen tip, following the outline of the ink mark. Wipe excess with a clean, soft white cloth. Only use Hi-Tech Magna MARK Professional Ink Remover on leather surfaces that have a top coat finish.
Not for use on suede, raw hide or pigskin.
