Top Star – protection for plastic and rubber

Top Star cares for plastic and rubber details in your vehicle’s interior. Its special emulsion protects against UV rays and dirt while giving surfaces a silky matte finish. Its antistatic effect helps prevent dust buildup, keeping the interior cleaner for longer, and it also freshens the interior with a subtle fragrance.

Leather Care – leather care

Leather Care restores leather’s natural appearance, enhancing its color and texture while maintaining a matte, non-glossy finish. The leather stays soft and pleasant to the touch, with no slippery feel, and the fresh fragrance adds a pleasant touch to the interior.

Mehrzweckreiniger – all-purpose cleaner

Mehrzweckreiniger is an effective cleaning product that easily removes grease, ink, soot, and smoke residue. It is suitable for plastics, upholstery, carpets, and leather, and leaves behind a fresh scent.

Pol Star – cleaner for textiles, leather, and Alcantara

Pol Star penetrates deep into the fibers and removes dirt without leaving streaks. It also impregnates the material and protects it against future soiling. Its neutral pH makes it safe for leather and Alcantara.

Gummifix – protection for rubber and plastic components

Gummifix cares for plastic and rubber components in the interior, including rubber carpets, floor mats, pedals, and plastic floors where slip resistance must be maintained. It contains no silicone and leaves materials looking natural.
