COLOURLOCK Leather Cleaner (Mild) — Gentle Cleaner for Regular Leather Care

What can COLOURLOCK Leather Cleaner Mild do? — The cleaner gently removes everyday dirt, light grease, and signs of wear from pigmented smooth leather, preserving its natural, matte surface without drying it out.

COLOURLOCK Leather Cleaner (Mild) is the first choice if you want to clean pigmented smooth leather regularly and in a material-friendly way. The formula is based on proven COLOURLOCK technology and safely removes light to medium soiling without attacking the leather's protective layer. Perfect for steering wheels, seats, armrests, entry areas, or furniture leather that should look well-maintained without the need for a strong cleaner. Mild is your "Everyday Cleaner" – ideal for new, well-maintained, or slightly soiled surfaces.

• Gentle everyday cleaning – Reliably removes light grease, dust, abrasion, and everyday dirt.
• Gentle on the surface – Preserves the matte OEM look and does not dry out the leather.
• Optimal for regular care – Ideal as a pre-treatment before leather care or friction protection.

Cleaning Mechanism & Material Protection on Smooth Leathers

Leather Cleaner Mild uses particularly fine surfactants that controllably dissolve dirt from the pigmented leather surface. Modern automotive leathers have a PU topcoat that somewhat repels dirt, but still collects grease and light abrasion particles over time. The mild formula breaks down these deposits without stressing the topcoat or altering its breathability. According to the manufacturer, Mild is ideal for maintaining the natural matte finish and feel — an advantage over cleaners that are too strong, which can lead to dry, dull leather with frequent use. Mild does not remove heavy residues, but it does remove everything that accumulates in everyday life.

Preparation, Application & Meaningful Cleaning Routine

Before cleaning, wipe the leather briefly with a dry microfiber cloth. Then apply the Mild Cleaner to a cleaning pad, sponge, or soft brush — never directly onto the leather. Work the foam in with circular movements until the surface is evenly clean. Remove residues with a slightly damp microfiber cloth. For heavily touched areas like steering wheels or seat bolsters, a second pass is useful if needed. Mild is ideal for use every one to four weeks, depending on use. Afterwards, the leather should be conditioned or protected so that the freshly cleaned surface is less susceptible to new dirt.

Results, Areas of Application & Distinction from Strong Cleaner

After treatment, the leather appears clearer, duller, and more natural. The surface feels grippy again, without a greasy finish. Mild is particularly suitable for new vehicles, freshly maintained interiors, furniture, and light soiling. If the leather is noticeably greasy, shiny, or heavily soiled, Leather Cleaner Strong works more efficiently — Mild is deliberately designed as a gentle everyday partner. It does not replace color refreshing or structural repair: for scratches or pigment loss, products like Leather Fresh are optimal.
