COLOURLOCK Leather Cleaner (Strong) — Powerful Deep Cleaner for Heavily Soiled Leather

What is COLOURLOCK Leather Cleaner Strong suitable for? — The cleaner thoroughly removes stubborn dirt, grease, abrasion, and deep-seated impurities from pigmented smooth leather, without drying out or attacking the surface.

COLOURLOCK Leather Cleaner (Strong) is your reliable, intensive leather cleaner for heavily soiled, greasy, or long-neglected smooth leather surfaces. The formula originates from professional COLOURLOCK technology and dissolves deep-seated deposits where mild cleaners are no longer sufficient. Perfect for steering wheels, seat bolsters, armrests, entry areas, and all zones that are particularly stressed in daily use. Despite its high cleaning power, the formulation remains gentle on materials and ensures that the leather retains its natural finish.

• High Cleaning Performance – Efficiently dissolves heavy soiling, body oils, color abrasion, and old care films.
• Gentle on Materials – Cleans intensively without drying out the top leather or damaging the pigment layer.
• Ideal for Heavy Wear and Tear – Perfectly suited for steering wheels, heavily touched seating surfaces, and long-neglected leather interiors.

Cleaning Mechanism & Functionality of Strong Leather Cleaners

Leather Cleaner Strong uses powerful yet leather-compatible surfactants that loosen dirt, grease, and deep-seated particles from the pigmented surface. Since modern automotive leathers have a PU topcoat, greases and abrasions often accumulate in the microstructures of this layer. The cleaner breaks these bonds without dissolving the protective layer. According to the manufacturer, the formula is designed to be powerful enough for stubborn residues, but gentle enough to preserve the matte factory look. Especially on shiny steering wheels, its efficiency is evident: the cleaner extracts the greases from the structure and restores the original grip and matte appearance.

Preparation, Application & Best Cleaning Routine

Before working with Leather Cleaner Strong, remove loose dirt with a microfiber cloth. The cleaner is applied to a cleaning pad, brush, or cloth — never directly onto the leather. Work the foam in with circular motions until the dirt dissolves. Then, remove the residue with a clean, slightly damp cloth. For particularly greasy areas like steering wheels, a repeat application may be necessary. After every intensive cleaning, a suitable conditioner or friction protection is recommended so that the leather remains supple and future soiling is less likely to adhere.

Results, Typical Applications & Differentiation from Mild Cleaners

After treatment, the leather appears cleaner, more matte, and feels significantly more tactile. Heavy soiling, glossy spots from skin oils, and embedded abrasion are significantly reduced or completely removed. The Strong Cleaner is particularly suitable for heavily used vehicles, detailing, lease returns, or older interiors. For light soiling, however, the mild version is sufficient to clean the surface gently. The Strong Cleaner does not replace scratch or color correction — for visible wear in the pigment layer, products like Leather Fresh or Fluid Leather are suitable.

Frequently Asked Questions about COLOURLOCK Leather Cleaner (Strong)

Can I use the Strong Cleaner on all types of leather?

Only on pigmented smooth leather. For aniline, nubuck, or sensitive leathers, the mild cleaner or a special product is more suitable.

Does the cleaner affect the color?

No, not on pigmented leathers. It removes dirt and grease without dissolving the color layer.

How often can I use the Strong Cleaner?

Only when needed. For regular care, the mild cleaner is sufficient.

Why does the leather become duller after cleaning?

Because greases and dirt that previously caused gloss are removed. This is a normal, desired result.

Do I need to condition after cleaning?

Yes. A conditioner or friction protection stabilizes the result and reduces new soiling.
