How do you clean a fogless shower mirror with an anti-fog coating?
To remove dust or any dirt on the mirror, gently wipe it with a dry soft cloth. However, we recommend wiping your mirror only when necessary, so that the anti-fog coating does not prematurely wear off. Let the mirror air dry after every use.
Do not clean it with anything like vinegar, shaving cream, white toothpaste, or soap because the more stuff the anti-fog chemical interacts with, the quicker it depletes.
Though these products can be used as cleaning agents, they're not advisable for cleaning anti-fog mirrors as these can cause the coatings to wear off prematurely.
