Chemical Guys Glass Cleaner Signature Series - Ammonia-Free Window and Mirror Spray Review
Chemical Guys Glass Cleaner earns a 45/100 CGR Score — it left visible streaks on every surface we tested. We purchased this ammonia-free formula hoping it would be safe for the Touareg's tinted rear glass, but the first spray on the windshield revealed major issues. Streaks appeared before we finished wiping. We repeated the test with three different microfiber towels and got identical results. After documenting the failures, we used the remainder on side mirrors and returned to Invisible Glass for reliable clarity.
Chemical Guys Glass Cleaner scores 45/100 CGR Score after leaving visible streaks on our 2014 VW Touareg windshield in three separate tests. Not recommended despite the ammonia-free formula.

Frequently Asked Questions
Is Chemical Guys Glass Cleaner worth buying for tinted windows?
It won't damage tint because it's ammonia-free. But it streaks on tinted rear glass worse than on clear windshields. We tested it on the Touareg's factory tint and had to go over it twice with a different product to fix the haze.
Does Chemical Guys Glass Cleaner streak on car windshields?
No. Invisible Glass removes film in one pass and leaves zero streaks in direct sunlight. Chemical Guys required three wipes on the same section and still left visible marks. We switched back after one bottle.
What's the best ammonia-free glass cleaner for cars?
The formula doesn't evaporate cleanly. It leaves a residue that shows up immediately under Wisconsin summer sun. We used fresh microfiber towels and proper technique — the product just doesn't perform.
