Lincoln Leather Dye is sometimes referred to as "oil dye" or aniline dye" or "penetrating dye," and is used to restore or change the color of leather by penetrating deeply into the leather. When Lincoln Leather Dye is used to restore color, all built-up polish and dirt should be removed with Lincoln Dye Preparer. When dying a shoe to a new color, the old color should first be stripped off by using Lincoln Dry Cleaner and Spot Remover. Lincoln Leather Dyes are available in 23 fashion colors for dyeing shoes and other leather articles.
