Dual Microfiber + Water Streak-Free Mirror Technique

"Ditch the blue glass cleaner and paper towels — one damp microfiber cloth plus a dry one gets mirrors 100% streak-free in half the time."
The science
-
Why plain water works
Split microfiber filaments carry thousands of wedge-shaped tips that grab oil and dust via capillary action and static charge, lifting residue that paper towels just smear around. For routine glass grime, that mechanical action is enough — no surfactant required.
-
Where it falls short
Heavy hairspray overspray or greasy cosmetic film is polymer and oil-based. Plain water can't cut that; it needs a drop of alcohol or dish soap worked in first, or you'll just push the residue around instead of lifting it.

The lint-free trick
Using two cloths — one damp to dissolve the grime, one bone-dry to buff — mimics the two-pass technique professional window cleaners use, keeping lint and drip streaks from redepositing as the glass dries.
Do it right
For hairspray or cosmetic buildup, add one drop of rubbing alcohol or dish soap to the damp cloth first, then buff dry with the clean microfiber as usual.
Where this came from
From the Clean Report hacks libraryThe Window Cleaning Academy / Professional Cleaner Network
"Wipe mirrors with one wet microfiber cloth using only warm water, then immediately buff dry with a second clean glass microfiber cloth for streak-free glass in half the time."
