Koch Chemie Allround Window Cleaner

Streak-free windows are not just about looks, they are a safety issue. The Koch Chemie Allround Window Cleaner is a ready-to-use alkaline glass cleaner that removes grease, oil, salt residue and fingerprints from glass without rinsing or diluting. The formula works on windscreens and rear screens from the inside, side windows, boat glass and polycarbonate. After use, no sticky residue remains, which means less dust attraction over time. The mild pH is safe on paint, so you can also work around window seals without risking damage to the paintwork or rubber. Available in 1 L for regular home or garage use. Spray onto a clean microfibre towel, wipe in overlapping passes and buff dry with a second towel. Particularly effective on interior glass that hazes over from dashboard plastic outgassing.

How to use

1. Spray onto a microfibre towel (Apply 2-3 pumps of Koch Chemie Allround Window Cleaner onto a clean, dry microfibre or glass towel. Do not spray directly onto hot glass or in direct sunlight.)

2. Wipe the glass in overlapping passes (Wipe horizontally or vertically in overlapping strokes across the glass. For interior windscreen work, divide into quarters to reach all areas without blind spots.)

3. Buff dry with a second dry towel (Use a second dry, lint-free microfibre towel to buff away remaining moisture. This delivers the streak-free result.)

4. Check in raking light (Inspect the glass in raking or back light to spot any remaining streaks or smears. Repeat locally if needed.)

Pair with a Koch Chemie Pro Glass Towel or D-CON Waffle Weave glass towel for a streak-free finish, and consider D-CON Ceramic Glass Clean & Protect for hydrophobic protection after cleaning.
