Koch Chemie Glass Cleaner is designed for detailers and enthusiasts who want clear, streak-free glass without wasting product. As a concentrate, it can be diluted to suit the cleaning task, making it an economical choice for regular glass maintenance.

Automotive glass collects a mix of contamination, including fingerprints, interior film, air conditioning residue, road grime and water marks. Glass Cleaner helps cut through this residue to restore clarity on windscreens, mirrors and side glass.

For best results, use with a dedicated glass towel and work methodically. On exterior glass that needs more than routine cleaning, pair with Koch Chemie Finish Spray Exterior for light mineral marks or use a deeper glass polishing process where required.

Pro Tip

Clean the exterior glass in horizontal passes and the interior glass in vertical passes. If streaks remain, you can quickly tell which side of the glass needs another wipe.
