COLOURLOCK GLD Solvent — Special Remover for Discoloration on Leather

What is COLOURLOCK GLD Solvent used for? — This powerful cleaner dissolves stubborn discolorations, color transfers, and old coating residues on leather, allowing for safe, controlled further processing.

COLOURLOCK GLD Solvent is a highly effective special remover that dissolves discolorations, color transfers, old paint layers, or difficult-to-remove residues on pigmented leather. GLD Solvent particularly shows its strength with dark denim rub marks, stubborn color transfers, sticky surfaces, or preparation for repairs. It carefully opens the top layer and optimally prepares the leather for color corrections, repairs, or re-sealing.

• Strong Solvent Effect – Removes color transfers, stubborn discolorations, and coating residues.
• Perfect for Repair Preparation – Makes the leather receptive to color and filler.
• Controlled Action – Dissolves without unnecessarily damaging the leather.

Solvent Technology & Mechanism of Action

GLD Solvent is based on a balanced, material-friendly solvent formula that dissolves color and dirt particles in the top leather coating. This allows problematic discolorations to be removed more effectively without penetrating deep into the leather structure. At the same time, the surface is slightly opened, allowing new color, filler, or binder to adhere optimally. The cleaner is ideal for automotive interiors, furniture leather, bags, and all pigmented smooth leathers that show discolorations or transfer stains.

Application, Coverage & Best Practices

Before application, the area should be clean and dry. GLD Solvent is sparingly applied to a cloth or pad and worked into the affected area in a controlled manner. Dissolved residues are wiped away, and the area is then neutralized. Depending on the discoloration, the process can be repeated. Important: work sparingly and do not rub unnecessarily. After use, the leather should be re-colored (Leather Fresh/Leather Color) and sealed with Top Coat.

Results, Areas of Application & Limitations

After treatment, stubborn discolorations, color transfers, and old coating residues visibly disappear or are completely removed. GLD Solvent is excellent for seat bolsters, steering wheels, furniture edges, bags, and delicate interiors. It is not an ordinary cleaner but a professional solvent for repair preparation. For extreme damage or deeply absorbed discolorations, a color correction is usually unavoidable.
