What product should I use to clean a fog-free shower mirror?
For a fogless shower mirror that uses anti-fog treatment, we do not recommend cleaning it with any cleaning agents as the anti-fog film is thin and sensitive, cleaning it can remove the coating.
For fog-free mirrors without anti-fog coating, some users recommend mixing an equal amount of distilled white vinegar and water then spraying it on the mirror surface, leaving it for 5-10 minutes then gently wipe it dry with a microfiber cloth. No need to rinse it with water.
Aside from vinegar, some users also recommend using small amounts of dish soap, shampoo and body wash to clean a fogless shower mirror without anti-fog coatings.
Avoid cleaning your mirror with harsh chemical cleaners that are intended for cleaning your bathroom sink.
