In the Lab, we apply the cleaners to black glass panels that we’ve smeared with greasy fingerprints, lipstick marks, household dust and other everyday stains (think the toothpaste that you accidentally squirted on your bathroom mirror). To find out which glass and window cleaners are best and to produce helpful window cleaning advice and tips, like the common mistakes to avoid when cleaning your windows, our Good Housekeeping Institute’s Home Care and Cleaning Lab experts evaluate multiple brands every year both in the Lab and at home. A good glass cleaner is a must-have in any cleaning arsenal and it should be one that cuts grime quickly and is easy and neat to use.

While you might not even notice a little spot on your carpet or fingerprints on a wall, a smudged, splattered, filmy glass surface, mirror or window can be very obvious and bothersome. We also added information about how we test and answered frequently asked questions on window and glass cleaners. This story was updated in October 2022 to add new picks, based on testing by the Good Housekeeping Institute Home Care and Cleaning Lab.
