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 and cleaning it can remove the coating.
For fog-free mirrors without anti-fog coating, mix equal amounts of distilled white vinegar and water, spray on the mirror surface, leave for 5 to 10 minutes, then gently wipe dry with a microfiber cloth. No need to rinse with water.
Aside from vinegar, some users also recommend using small amounts of dish soap, shampoo, or body wash. Avoid harsh chemical cleaners intended for your bathroom sink.
