Koch-Chemie Mild Clay Bar – Gentle Decontamination for Paint and Glass
The Koch-Chemie Rkb mild clay bar is designed for gentle yet effective removal of bonded surface contaminants. It safely removes tree resin, insect remains, rust bloom, industrial dust, spray mist, tar and light limescale stains from smooth surfaces without damaging paint or glass.
Unlike aggressive clay bars, this mild clay bar cleans thoroughly while preserving surface integrity. Therefore, it is ideal for regular maintenance and pre-polishing preparation.
Ideal for Safe Surface Preparation
Over time, even well-maintained vehicles accumulate bonded contaminants that cannot be removed through standard washing. As a result, polishing results may be reduced and surface smoothness compromised.
The mild clay bar eliminates these residues and restores a smooth finish, making it optimal for preparation before polishing or before installing new windscreen wipers.
Suitable Surfaces
-
Automotive paintwork
-
Glass surfaces
-
Smooth exterior panels
