For light-colored smooth leathers or artificial leathers, discolouration can occur from items like jeans, belts, bags (both leather and fabrics), or pens. These stains are common on furniture and vehicle upholstery. If not promptly cleaned, the dyes can penetrate the surface and become impossible to remove with regular cleaners. The GLD solvent ND can be used to attempt the removal of such stains when gentler cleaners have failed.
Typically, 250 ml of GLD ND is sufficient as it is a specialized cleaner with a dissolving effect. For experienced users requiring larger quantities, the liter of GLD ND is recommended.
