We decided to use Eric Stafford's 1997 Chevrolet Camaro Z/28, with its massive tinted rear glass, for our side-by-side test. While this is frustrating, it made it easy for us to find properly grubby windows among the usually sparklingly clean Car and Driver fleet. All it takes is a bit of rain or a dust-bunny-induced sneeze, and it's due for a cleaning.

As we ran them through the Gear Team testing gauntlet, we determined which ones work best. To find which product best cleans windows, we assembled 10 different cleaners and got to work. While that sounds great, we found that it takes a bit more effort to properly apply, and there's no sense in using it on your other windows. These leave a hydrophobic film on your windshield that allows water droplets to slide right off, even to the degree where you don't need to use your wipers. You'll also see ceramic glass cleaners pop up when searching around. Most automotive glass cleaners are ammonia free and say so right on the bottle, but it's always a good idea to verify. Ammonia can break down window tint-especially the cheaper stuff-so if you're not a fan of the fishbowl look, stay away from ammonia. Right off the bat, we'll tell you this: Using an ammonia-free glass cleaner is a must. Keep out of reach of children.Show more Considerations on Automotive Glass Cleaners Do not get in eyes, or on skin or clothing.
