Koch Chemie InsideUp is designed for quick and effective cleaning of hard plastic interior surfaces. Modern interiors include dashboards, consoles, door trims, lower plastics and textured panels that collect dust, fingerprints and daily grime. InsideUp provides a straightforward cleaning step that refreshes these surfaces without leaving an artificial shine.

This makes it ideal for regular maintenance cleaning, dealership presentation and professional interior details where a clean, natural look is required. After cleaning, surfaces can be protected or dressed with Koch Chemie InsideCare or Top Star depending on the desired finish and level of protection.

For heavier soiling, use Koch Chemie Mehrzweckreiniger or Green Star at a suitable dilution first, then finish with InsideUp for lighter maintenance.

Pro Tip

Use a soft detailing brush on textured plastics and seams, then wipe with a towel. This removes dirt from grain that a flat towel can miss.
