Cleaning windows streak-free: How to really make streaks disappear

Streaks are almost never caused by using too little cleaner—but by using too much of it and the wrong cloth. If you clean glass in two steps with a clean, slightly damp microfiber cloth—wipe once to loosen the dirt and then dry with a second cloth—you’ll get streak-free windows without any special products. Everything else is just technique.

Why do streaks form when cleaning windows?

Streaks are residue. Usually, they’re left by cleaner that hasn’t been completely removed. Or by hard tap water that dries and leaves limescale behind. Or by a cloth that merely spreads the dirt instead of absorbing it.

Cotton rags and paper towels leave lint and smear the film across the pane. Then there’s the classic mistake: cleaning in direct sunlight. The water dries faster than you can wipe it dry—leaving exactly the kind of edges you want to avoid.

Cleaning windows without streaks—step by step

1. Wipe off loose dust while it’s dry so it doesn’t leave streaks later.
2. Dampen the pane with a little lukewarm water and a squirt of cleaner. Less is more.
3. With a damp microfiber cloth, wipe down in sections from top to bottom.
4. Immediately follow up with a second, dry microfiber cloth—before the water dries.
5. Finish with the corners and frames. Don’t work in the sun.

The crucial step is switching to a dry cloth. One cloth for dampening, one for drying—that’s the whole trick.

Microfiber cloth instead of newspaper and paper towels

Newspaper works, but leaves printer ink on hands and frames. Paper towels leave lint and tear as soon as they get wet. In contrast, a tightly woven microfiber cloth absorbs water and film instead of spreading them—and can be washed again and again.

Our set of two microfiber cloths is designed exactly for this: one for dampening, one for drying. It’s the two-cloth technique that prevents streaks.

Do you even need glass cleaner?

For normally soiled windows, lukewarm water with a drop of dishwashing liquid is enough. A special glass cleaner is especially worthwhile for greasy panes, such as in the kitchen.

The dosage is more important than the product. Too much cleaner is the most common cause of streaks. Spray one squirt onto the cloth, not the entire pane. If you prefer alcohol-free cleaners, choose a mild solution—a streak-free finish depends on drying with a dry cloth anyway.

Hard water: the underestimated cause

In regions with hard water, even clean panes can dry with spots. Two things help: wipe the pane dry quickly so the water doesn’t have time to dry on the glass. And for stubborn limescale, add a dash of clear household vinegar to the cleaning water. Then wipe again with clear water and dry.

Mirrors and glass surfaces in the bathroom

The same technique applies to mirrors, shower screens, and glass shelves. For limescale spots on shower glass, it helps to wipe dry with a dry cloth immediately after showering—this prevents the limescale from setting in the first place. This keeps the glass clear for longer without any scrubbing.

How often should you clean windows?

Two to four times a year is enough for most households. If you live on a busy road or have pets, you’ll need to clean them more often. In between, simply wiping mirrors and interior panes briefly with a dry microfiber cloth is enough.

In short

Two cloths, a little water, and no cleaning in the sun. That’s all you need for streak-free windows. The right cloth makes the difference—over 450,000 people rely on nordesign textiles every day.
