How to Clean Mirrors Without Streaks

There are few things more annoying than cleaning a mirror, stepping back, and seeing a web of streaks staring back at you. The good news? Streaks are almost never about how hard you clean. They're about what you're cleaning with.

Why your mirror keeps streaking

• Too much product. Glass cleaner that doesn't get fully wiped away dries into a film.
• The wrong cloth. Paper towel and old cotton rags leave lint, and anything washed with fabric softener smears a waxy residue across the glass.
• A dirty cloth. If your cloth has been wiping benches all week, it's just moving grime from one place to another.
• Hard water. Tap water with lots of minerals can leave spots as it dries.
• Direct sun. Cleaning glass in bright sunlight makes it dry before you can wipe it off.

How to clean a mirror without streaks

1. Dust it first. Give the mirror a quick wipe with a dry cloth to remove dust and lint.
2. Spot treat the gunk. Toothpaste splatters and hairspray build-up need a bit more. Dab them with a cloth dampened with equal parts white vinegar and water, and let it sit for a minute.
3. Dampen your cloth, not the mirror. Wet a clean cloth with water and wring it out well. Spraying directly onto the mirror lets liquid run down into the edges, which can damage the backing over time and cause those dark patches around the frame.
4. Wipe in an S pattern. Start at the top corner and work across and down in a zigzag.
5. Buff dry. Go over it with a dry, clean, lint-free cloth (or the dry side of your cloth) to finish.

Can you really clean a mirror with just water?

For everyday dust, fingerprints and splashes, yes, as long as your cloth is up to the job. A good cleaning cloth grabs the grime instead of smearing it, so you don't need a spray to do the work. Save the vinegar mix for toothpaste, hairspray and anything greasy.

DirtyGirl cleaning cloths are designed to be lint-free and streak-free on glass and mirrors, and they work with just water. One cloth damp, one dry, and you're done.

Bathroom mirror tips

• Clean it when it's not steamy. Wiping a fogged-up mirror just smears condensation around.
• Keep a cloth in the bathroom. A 20-second wipe after you brush your teeth stops splatter from building up.
• Don't forget the edges. Soap and product collect where the mirror meets the frame or splashback.

The cloth matters more than the spray

If you take one thing from this post, let it be this: never wash your glass cloth with fabric softener. It coats the fibres and leaves a film on every surface it touches, which is why so many people blame their glass cleaner when the real culprit is the cloth. Wash with regular detergent, and add a splash of vinegar instead of softener.

Mirror cleaning FAQs

Does newspaper really clean mirrors without streaks?

It was the go-to for generations, but modern newspaper ink can transfer onto frames and grout. A lint-free cleaning cloth does a better job without the mess.

Why does my mirror still streak after using glass cleaner?

Usually too much product, a cloth with softener residue, or a cloth that isn't absorbent enough to pick it all up. Try water and a clean lint-free cloth instead.

What's the best homemade mirror cleaner?

Equal parts white vinegar and water in a spray bottle. Spray it onto your cloth rather than the mirror.

How do I clean an antique or framed mirror?

Use as little moisture as possible and keep liquid well away from the edges and frame. A barely damp cloth followed by a dry buff is the safest option.
