Quick answer

Why is my bathroom mirror so streaky after I clean it? Almost always it is leftover cleaner, a dirty or lint-shedding cloth, or hard water minerals drying into lines. Wipe with a lightly damp cloth and a little cleaner, then buff with a second clean, dry cloth. Low-lint microfiber glass cloths and a streak-free cleaner leave no lines.

Free fix vs. permanent fix

Free fix · 5 minutes

Vinegar-water and a lint-free cloth

  • Mix equal parts white vinegar and water
  • Spray the cloth, not the mirror
  • Wipe in overlapping strokes
  • Buff dry with a second clean cloth

How long it lasts: One clean. The streaks come back if the cloth is dirty or has softener in it.

Low-lint microfiber glass cloths

Streaks often come from the cloth, not the cleaner. Glass cloths are woven to lift film and moisture and shed little lint, and a second dry cloth buffs the glass clear. Keep a pair just for mirrors, and they stay clean.

What to get: Microfiber glass cleaning cloths

How long it lasts: Years, if you wash them without fabric softener.

Why it happens

1

Too much cleaner

Cleaner dries as a film. A mirror needs only a light mist, not a soaked cloth.

2

A cloth that leaves something behind

Cotton towels shed lint. A cloth washed with fabric softener or a dryer sheet smears a waxy residue. An old sponge pushes dirt around.

3

Hard water minerals

Tap water in a spray or a rinse leaves mineral spots and lines as it dries.

4

Oily film from hairspray and soap

Hairspray, toothpaste splatter and soap leave a sticky layer that smears into a haze.

5

Cleaning a warm mirror or in strong sun

Cleaner dries before you can wipe it off, and that leaves streaks.

Do these in order, starting with the simplest.

  1. Dust the mirror first

    Tool used: Microfiber glass cloths

    Wipe the dry mirror with a dry cloth, so dust does not turn into mud when it gets wet.

  2. Mix a light cleaner

    Tool used: White vinegar

    Fill a spray bottle with equal parts white vinegar and water. If your tap water is hard, use distilled water for the mix.

  3. Spray the cloth, not the mirror

    Tool used: Spray bottle

    Mist the cloth until damp, not dripping. Liquid that runs down the glass can seep behind the edges and damage the mirror backing over time.

  4. Wipe in overlapping strokes

    Work from top to bottom with slightly overlapping strokes, so you do not leave a dry strip. Do the corners and edges last.

  5. Buff dry right away with a second cloth

    Tool used: Microfiber glass cloths

    Use a dry glass cloth and buff in small circles until it squeaks. Do this before the cleaner dries by itself.

  6. Wash your cloths the right way

    Wash microfiber alone in warm water, with no fabric softener or dryer sheets. Dry on low or air-dry, and keep them apart from lint-shedding towels.

When free fixes aren't enough

If the mirror still looks hazy after a vinegar wipe, the haze is built-up film. Try a drop of dish soap in a cup of warm water to cut it, then wipe with a cloth dampened in plain water and buff dry. If cloudy spots or black marks will not wipe off, or they sit at the edges or behind the glass, the silvering is damaged and no cleaner will fix it. A ready-made glass cleaner helps when you would rather not mix your own, or your tap water leaves spots even with vinegar.

Pick the right time to clean

Clean when the mirror is cool and out of direct sun. Run the fan first so the steam clears, because wiping a fogged mirror leaves lines. A short pass with a dry cloth right after you finish prevents most streaks.

Hard water in your taps? Finish with distilled water

If your tap water is hard, even a perfect wipe can dry into tiny white dots. For the last pass, dampen a clean glass cloth with distilled water and buff the mirror dry right away. Distilled water has no minerals to leave behind. One jug lasts for many mirror cleanings, so the cost is small.

What to skip

Paper towels and spraying the glass directly

Paper towels shed lint that sticks to a wet mirror. Spraying straight onto the glass lets liquid run behind the edges, which can start black spots later.

Frequently asked questions

Why is my bathroom mirror foggy after cleaning?
A hazy film after cleaning is usually cleaner residue or a soapy, oily layer you smeared around. Wipe again with a cloth dampened in plain water, ideally distilled, then buff dry. Use less product next time.
Why is my bathroom mirror cloudy?
Steam, hard water minerals and hairspray build a film over time. Vinegar water breaks up minerals, and a drop of dish soap in warm water cuts oils. Cloudy patches that start at the edges point to worn silvering.
Is vinegar safe on a bathroom mirror?
Diluted vinegar is fine on glass. Do not let it sit on metal frames or run behind the mirror.
How often should I clean the mirror?
Once a week keeps film from building. If you use hairspray near it, wipe it more often.
What should I never use to clean a mirror?
Skip paper towels, which shed lint, and abrasive sponges, which can scratch the glass. Skip any cloth washed with fabric softener, since it smears a waxy film. A clean, damp microfiber cloth and a dry one are all a mirror needs.
