We Say

Glass surfaces on vehicles are among the most scrutinised areas — streaks, smeared residue and leftover oils show up instantly in sunlight, and ordinary cleaners often struggle to fully remove ingrained grease, bug residue and garage grime without leaving smears.

What we like about Koch Chemie GC Glass Cleaner is that it addresses this specific challenge with a simple, ready-to-use formula that combines strong dirt removal with extremely fast flash-off and virtually no streaking. The chemistry is engineered to lift common contaminants like oil, insects and brake dust without leaving behind solvent residue that can blur reflections or require repeated wiping.

In practical use, GC is easy to employ: spray directly onto glass or your microfibre towel, work methodically from one side to the other, and let the cleaner do the heavy lifting. Because it contains a smoothness additive that improves cloth glide and reduces drag, you spend less time buffing and more time achieving pristine clarity.

For anyone who demands truly streak-free glass — especially on windscreen edges, rear windows and around mirrors — this product delivers fast, reliable results with minimal effort. Its balance of cleaning strength and wipe-off ease is exactly what separates a capable glass cleaner from a mere “decent” one.

Description

Koch Chemie GC Glass Cleaner is a ready-to-use automotive glass cleaner formulated to remove the most stubborn contaminants from smooth surfaces without smears or streaks. Designed for use on vehicle windows, mirrors and other smooth surfaces, this cleaner effortlessly cuts through ingrained dirt, oil, grease, fingerprints and insect matter with a formulation that flashes off quickly and leaves a clean, optically clear surface.

The product’s solvent blend is optimised for high-efficiency cleaning without over-aggressive solvents that can dry too fast and trap residue. Instead, GC balances evaporation rate with lifting power, meaning that it loosens stubborn debris effectively while remaining workable long enough to ensure full removal. In addition to automotive glass, it is suitable for other smooth surfaces such as mirrors, tiles and sheet metal, making it versatile in workshop environments.

One of the standout characteristics of GC Glass Cleaner is its streak-free performance. The formulation incorporates a smoothness additive that enhances microfibre cloth glide and reduces the need for repeated wiping passes. This additive helps maintain a crisp, reflective finish even under bright sunlight or strong LED inspection lights.

GC is supplied ready to spray and does not require dilution. Simply mist the cleaner directly onto the surface or onto a quality glass microfibre towel, then wipe and buff to clarity. Its fresh but unobtrusive fragrance and fast flash-off make it particularly user-friendly for rapid interior and exterior glass cleaning.

Whether used as part of a weekly maintenance routine or during pre-sale preparation, Koch Chemie GC Glass Cleaner provides professional-grade glass cleaning performance with minimal fuss, delivering clear lines of sight and mirror-like reflectivity that enhance both appearance and safety.

How To Use

GC Glass Cleaner is ready to use (no dilution). Work on cool glass out of direct sunlight.

1. Remove loose grit first to minimise scratching.

2. Spray the product neat onto the glass, or onto your towel for interior work.

3. Wipe methodically until smears are gone.

4. If streaks remain, repeat and finish with a second dry towel.

Pro tips

• Use the two-towel method (wipe + final buff).
• Swap towels when they feel saturated.
• For interior windscreens, work small sections and finish dry.
