- How to Clean Windows Without Streaks
The right cloth and the right cleaner only get you halfway there. Here’s the technique that actually stops streaks forming in the first place.
Spray an enzyme-based glass cleaner evenly across the pane, wipe with a lint-free microfibre cloth, then buff dry with a second dry cloth immediately after. Clean on a cloudy day or in shade so the cleaner doesn’t dry before you can wipe it off, which is what causes most streaks.
Streaks aren’t usually a sign you need a stronger product — they’re almost always a sign the cleaner dried on the glass before it was wiped away properly, or that the cloth you used left fibres behind. Fix the technique and most streaking problems disappear.
You need a lint-free microfibre cloth, a squeegee with a sharp rubber blade, a low-tox enzyme-based glass cleaner, and a dry buffing cloth. Skip paper towels and old t-shirts — they shed lint and fibres that stick to the glass and create the smudges you’re trying to avoid.
The biggest causes of streaky windows are cleaning in direct sun, using too much product, wiping in circles instead of straight lines, and drying with a lint-shedding cloth. Hard water left to air-dry also leaves mineral streaks, so always buff the glass dry rather than letting it dry on its own.
If you’re doing everything right and still seeing streaks, check the cloth first. Cloths that have been washed with fabric softener hold onto residue that transfers straight onto the glass, so wash your microfibre cloths separately with a small amount of detergent and no softener.
It’s usually leftover product that dried on the glass before being wiped off, often because you cleaned in direct sun or used too much cleaner. Buffing with a dry microfibre cloth straight after wiping solves this in most cases.
A lint-free microfibre cloth. Paper towels, old t-shirts and cotton rags all shed tiny fibres that stick to glass cleaner and show up as smudges once the window dries.
A cloth works fine for smaller panes, but a squeegee gives a cleaner finish on larger windows and sliding doors because it lifts the cleaner off in one pass instead of smearing it around.
Overcast days or early morning and late afternoon, when the glass isn’t in direct sun. Sunlight heats the glass and dries cleaning product before you can wipe it off, which is the single biggest cause of streaks.
Inside panes benefit from a wipe every 4-6 weeks, with a full inside-and-out clean twice a year. Homes near the coast or busy roads may need it more often due to salt spray and grime build-up.
Streak-free windows come down to technique more than product: work in the shade, use lint-free cloths, and always buff dry before the cleaner has a chance to air-dry on the glass.
