No mater how often you clean your shower doors, they always end up getting grimy. The simple secret that quarantines lasting sparkle? Trade your usual paper towels or cloth cleaning towel for a dryer sheet. Simple spray the shower door with glass cleaner, then wipe down with a dryer sheet. The sheet's tightly knit fibers get rid of stuck-on grime and spots better than towels, and the waxy surface gently coasts the glass with a water-resistant layer to deter buildup from forming. Repeat once a month.
