Invisible Glass Auto Glass Cleaner (Aerosol) vs Chemical Guys Signature Series Glass Cleaner Ammonia Free Spray
Which should you buy? Our verdict on both, pulled from our full The Best Car Glass Cleaners: 4 Compared (and One to Skip) comparison.
Invisible Glass wins because its maker publishes the specific claims that matter here, no ammonia and no added soaps, scents, or dyes, and the foam format suits vertical glass. Chemical Guys runs it close and pulls ahead if you want a gallon refill and one bottle for the car, the screens, and the house.

Invisible Glass Auto Glass Cleaner (Aerosol)
Buy itA foaming aerosol that clings to vertical glass, with the clearest ammonia-free and residue-free wording of anything here.
- The maker states it contains no ammonia, no high pH ingredients, and no hazy silicon-wetting agents.
- Foaming action keeps the product where you sprayed it instead of running down the window into the door seal.
- Invisible Glass says the formula has no added soaps, scents, or dyes and was tested residue-free by independent laboratories.
- An aerosol is harder to aim into the tight wedge at the base of a windshield than a trigger spray with a reach tool.
- The only larger option listed is a six-pack of cans, so there is no refill or concentrate to bring the per-clean cost down.
- The product page says nothing about ceramic-coated or otherwise treated glass, so you are on your own there.

Chemical Guys Signature Series Glass Cleaner Ammonia Free Spray
Buy itA ready-to-use trigger spray that puts the ammonia-free claim in the product name and sells a gallon refill behind it.
- Chemical Guys states the ammonia-free formula will not stain or damage window tints or clear plastics.
- Sold as a 16 oz bottle and a 1 gallon jug, so you refill the trigger bottle rather than rebuying it.
- The maker lists window tints, computer screens, LCD televisions, household windows, and Plexiglas as safe surfaces, so one bottle covers more than the car.
- Chemical Guys posts a California Proposition 65 warning for formaldehyde on this product page.
- A liquid trigger spray runs on vertical glass, so heavy road film takes more passes than a foam does.
- The gallon is a ready-to-use refill rather than a concentrate, so you are storing and shipping mostly water.
