2...

Air Freshener
cloth

EASY!!!
Spray Air Freshener on mirror
Wipe with Cloth
This is to brighten only! No More "Blur Mirror" After HOT BATH
What do you need?
Soap (ANY kind even your hand soap)
Cloth
Clean Water (Optional)
What should You Do?
Tap some soap on the cloth
Wipe the mirror with it
*You may use water to wipe through again after that, but not too much JUST A LITTLE. As too much water might remove the soap. Without the soap on the mirror surface, your mirror will still be foggy after hot bath
