We tested 10 different glass cleaners to find out which one is the best for your automotive needs.
Cleaning your car windows might seem like an afterthought—after all, that's what wiper blades are for, right? Sort of. While keeping the outside of your windshield clean and clear is essential, you shouldn't forget about the side windows, the rear window, and the inside of the glass all around the car.
Cleaning your vehicle's glass will greatly improve visibility; you might be surprised to see the difference after one good wipe-down. And of course, clear vision has safety benefits too. But there are a ton of glass cleaners on the market, so which one works best?
Right off the bat, we'll tell you this: Using an ammonia-free glass cleaner is a must. 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. Most automotive glass cleaners are ammonia free and say so right on the bottle, but it's always a good idea to verify.
You'll also see ceramic glass cleaners pop up when searching around. 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. 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.
To find which product best cleans windows, we assembled 10 different cleaners and got to work. As we ran them through the Gear Team testing gauntlet, we determined which ones work best.
Glass can be a fickle thing. All it takes is a bit of rain or a dust-bunny-induced sneeze, and it's due for a cleaning. While this is frustrating, it made it easy for us to find properly grubby windows among the usually sparklingly clean Car and Driver fleet. We decided to use Eric Stafford's 1997 Chevrolet Camaro Z/28, with its massive tinted rear glass, for our side-by-side test. Austin Irwin's Honda Civic Si also lent some windows.
We taped off 10 sections of the Camaro's large, dark rear glass and set to work. Our testing process was simple: liberally spray the section and wipe for 15 seconds with a clean microfiber towel. This gave us the opportunity to check each car glass cleaner for:
Comparing our detailed notes on these parameters allowed us to choose which glass cleaners were best and which fell short. Here are our top picks for the best automotive glass cleaners.
