COLOURLOCK Grease Absorber is a solvent gel mixed with an absorbent powder which is ideal for removing grease and sweat stains commonly found on armrests and headrests of old napa leather furniture. These stains are usually too intense to be removed using normal cleaning methods. Over time grease accumulates and penetrates the leather leaving unsightly stains in areas that come in direct skin contact. The paste absorbs all the grease from the leather allowing the subsequent colour coat to adhere to the surface. Leather treated with Grease Absorber Paste will need to be coloured or will require a colour touch-up.
