Invisible Glass 91164-2PK 19-Ounce Cleaner for Auto and Home for a Streak-Free Shine, Deep Cleaning Foaming Action, Safe for Tinted and Non-Tinted Windows, Ammonia Free Foam Glass Cleaner, Pack of 2

Invisible Glass 91164-2PK is an aerosol foam glass cleaner from Stoner, sold in a two-can set of 19-ounce containers. The formula is ammonia free and made without soaps, dyes or added scents, which is what keeps it from leaving a film behind on cleaned surfaces. Each can carries a model number of 91164-2PK and is produced in the USA.

In regular use, the foam holds its position on vertical glass instead of running off, giving the cleaner time to work on road grime, grease, mud, salt, fingerprints and smudges. It suits windshields, side windows, mirrors and chrome, along with household glass and stainless steel appliances. Because there is no ammonia in the mix, it can go on tinted glass as well as untinted, indoors or out.

• Two 19-ounce aerosol cans per pack
• Package dimensions: 5 x 9.5 x 2.5 inches, 1.2 pounds
• Store cans upright, away from heat

To get the best results, spray the foam directly onto the glass surface from a distance of about six to eight inches, let it dwell for a few seconds to loosen contaminants, then wipe with a clean microfiber cloth using overlapping strokes. Finish with a second dry cloth to catch any residue before it dries. For windshields with heavy buildup from wiper fluid or bug splatter, a second application on the same pass is often more effective than pressing harder on the first. Avoid using the product in direct sunlight or on hot glass, as rapid evaporation can work against the foam before it has a chance to lift the soil properly.

The two-can format makes sense for households that clean multiple vehicles or a mix of car windows and home glass regularly, since a single can can run short mid-project. When comparing foam glass cleaners generally, the key things to check are whether the formula is ammonia free for tinted window compatibility, whether it contains dyes or soaps that leave film, and whether the can is designed to spray upright only or in multiple positions. This product is well suited to anyone who details their own car, maintains a fleet of personal vehicles, or simply wants a single cleaner that works on both automotive and household glass without switching products.
