Koch Chemie Glass Star

The Koch Chemie Glass Star is a concentrated alcohol-based glass cleaner that quickly and effectively removes oil, grease, silicones, insects and stubborn marks from glass surfaces. The alcohol formula dries fast, which minimises the risk of streaks. Use it undiluted for heavy contamination, or dilute 1:3 with osmosis water for everyday maintenance where 1 litre expands to 4 litres of ready-to-use cleaner. Available in 1 L for regular use and 10 L for professional applications or high-volume use in garages, workshops, or commercial fleets. Koch Chemie specifically lists automotive glass, truck glass, and building windows as suitable applications, making Glass Star broadly versatile. Always use with a clean, lint-free microfiber cloth for the best streak-free result.

How to use

1. Choose your dilution based on the level of contamination (Use undiluted for heavy soiling like silicones or insects. Dilute 1:3 with osmosis water for routine maintenance.)

2. Spray the product evenly across the glass surface (Work in shade to prevent rapid evaporation. Apply an even layer without oversaturating. Work one pane at a time.)

3. Wipe the surface with a microfiber cloth in overlapping passes (Use a lint-free glass cloth or waffle-weave towel. Horizontal strokes outside, vertical inside, so you can identify which side any streaks are on.)

4. Buff to a final streak-free finish with a second dry microfiber cloth (Use a completely dry glass cloth to buff until streak-free. Check at a sharp angle in backlight and repeat if needed.)

Use the Glass Star together with the D-CON Waffle Weave Glass Window Towel for a streak-free finish, then apply D-CON Ceramic Glass Clean & Protect for a lasting hydrophobic glass coating.
