Koch Chemie InsideUp — Deep-Clean Interior Plastics Before You Protect Them

InsideUp is built for the unpainted plastics and rubber that take the most abuse inside a car — the cockpit, door cards, trim and rubber mats. It cleans deep into the textured pores where grime and skin oils collect, resetting the surface so a protectant can actually bond.

The first half of a two-step system

Clean, then care. InsideUp is step one; InsideCare is step two. Cleaning first matters because a dressing applied over embedded dirt just seals the grime in — strip it back properly and the protection lasts longer and looks better.

How to use it

Spray onto a soft cloth, work the surface, allow a brief dwell, then wipe down with a clean damp cloth and dry. On heavily soiled textured plastic, a soft detailing brush helps lift dirt out of the grain. Follow with InsideCare to protect the freshly cleaned surface.
