All rubbing compounds contain an abrasive powder which controls the abrasion of the paint. This powder can settle in the pores of the plastic parts. This polish residue can be easily removed with the microfibre cloth and the cleaning and control spray. Simply spray the cleaner onto the soiled plastic part and wipe off with the cloth. Alternatively, a window cleaner with ammonia can also be used for cleaning (SHINE or ICE). A more time-consuming solution involves the use of masking tape prior to polishing. This is especially recommended when polishing new vehicles. Avoid contact with plastic parts when polishing. We also recommend using as little polishing compound as possible in order to prevent the compound from splattering.
