Streaky windows are almost never about how hard you scrub; they come down to timing, the right tools, and a repeatable technique. The video above shows the professional method in action, and this guide breaks it down into clear, ordered steps you can follow at home, in a holiday rental, or across a hotel floor. It is written with Greek conditions in mind, where strong sun and coastal dust make truly streak-free glass harder to get than you would expect.
Why windows streak in the first place
Streaks are dried residue: leftover cleaning solution, mineral deposits from hard water, or dust that gets smeared rather than lifted. When the glass dries faster than you can wipe it, that residue sets into the visible lines and cloudy patches you are trying to avoid.
In Greece this effect is amplified. Intense Mediterranean sun heats the glass and flash-dries any solution within seconds, while salty coastal air and fine dust leave a film that a quick spray-and-wipe simply pushes around. Controlling drying time and water quality matters more here than in cooler, damper climates.
What you actually need
You do not need expensive products. A squeegee with a sharp rubber blade, one or two microfibre cloths, a soft sponge or scrubber, and a bucket of clean water with a single drop of dish soap will outperform most aerosol glass cleaners. The soap helps the squeegee glide; too much causes streaks, so keep it minimal.
For holiday rentals and hotels with many windows, the bucket-and-squeegee method is faster and far more consistent than spray bottles, and it uses less product per pane. Keep a separate dry microfibre cloth just for detailing the edges, the small step that separates an amateur finish from a professional one.
The streak-free method, step by step
- 1
Work in the shade, never direct sun
Pick a cool part of the day or a window that is currently shaded. Direct Greek sun dries the solution before you can squeegee it, which is the single most common cause of streaks. Early morning or late afternoon is ideal.
- 2
Dust and pre-clean the frame and track first
Wipe loose dust, cobwebs and grit off the frame and from the track or sill before touching the glass. If you wet dirty glass straight away you create mud that smears, and grit caught under your cloth or squeegee can scratch the pane.
- 3
Wash the glass with a soapy sponge
Dip your sponge or scrubber in the bucket (clean water plus one drop of dish soap) and wet the whole pane, working top to bottom. Loosen stubborn spots and bird droppings now. Keep the glass wet enough to glide, not flooded.
- 4
Squeegee in overlapping strokes, wiping the blade each pass
Start at a top corner and pull the squeegee down or across in a straight stroke. Wipe the rubber blade dry with a clean cloth after every pass, and overlap each new stroke into the cleaned area so no wet lines are left behind. This is the move that delivers the streak-free result.
- 5
Detail the edges and buff with dry microfibre
Run a dry microfibre cloth around the perimeter and into the corners where water collects, then lightly buff any remaining haze in the middle. Check the glass from an angle and from both sides, since streaks are easiest to spot with light raking across the surface.

FAQ
- What is the best homemade solution for streak-free windows?
- Clean water with a single drop of dish soap is enough for everyday cleaning and lets a squeegee glide. For hard-water spots or coastal film, a 50/50 mix of water and white vinegar cuts mineral residue well. Avoid using too much soap or product, as excess is what dries into streaks.
- Why do my windows still streak after cleaning?
- The usual culprits are cleaning in direct sun (the solution dries too fast), using too much product, or wiping with a dirty or non-microfibre cloth that redeposits residue. Work in shade, use minimal soap, and wipe your squeegee blade dry after every stroke.
- Should I use newspaper or paper towels to dry windows?
- Both are outdated. Paper towels leave lint and break apart when wet, and modern newsprint smears ink. A clean, dry microfibre cloth or a squeegee gives a far better, lint-free, streak-free finish and is reusable, which is better for both cost and the environment.
