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.

APPLICATION

Depending on the material, start by attempting to clean the surface with Leather Cleaner Strong or Cleaner for Artificial Leather. If unsuccessful, apply some GLD ND to a microfiber cloth and carefully clean the surface. Always test on a hidden area first! Some surfaces are easily dissolved (furniture leather), while others react more subtly (car leather, artificial leather). Carelessness with GLD ND can worsen the problem. When using GLD ND, the upper layer of leather colour is dissolved. Some leather dye may also be removed while trying to remove the discoloration, which will be visible on the cloth. Be cautious not to completely remove the colour layer. If colour removal occurs or the discoloration cannot be fully eliminated, these areas must be retouched with suitable Leather Fresh dye. Before cleaning with GLD ND, smooth roughened areas with COLOURLOCK Polishing Pad 4000. In approximately half of the cases, GLD ND alone is sufficient and colour matching is unnecessary. The more severe the discoloration, the higher the likelihood of requiring colour matching with Leather Fresh dye. Artificial leather is more challenging to clean than genuine leather. To prevent further discoloration, regularly protect the surface with COLOURLOCK Leather Shield. This product reduces dye penetration into the surface. To be safe, treat all previously unaffected contact surfaces with the leather shield. However, the shield should only be applied to surfaces previously cleaned with leather cleaner mild or strong.
