Cleaning glass seems simple until the sunlight reveals every streak. The key isn’t scrubbing harder, but controlling three factors: the water, the cloth, and the order of work. With these adjustments, your home’s windows come out transparent without the need for harsh products.
Prepare the surface before wetting
Dust and sand act like sandpaper on the glass. First, run a soft brush or a duster over the frame and the exterior side to remove dry particles. If the glass has limescale or kitchen grease residue, apply a mixture of warm water with a few drops of mild soap and let it sit for a minute. This way the main wash carries away the dirt without scratching.
The mixture that prevents white marks
Tap water concentrates minerals that leave films when they dry. An effective solution combines one liter of distilled water, a tablespoon of white vinegar, and two drops of dish soap. The vinegar dissolves limescale and the soap carries away grease. For very dirty glass, add a pinch of baking soda, but rinse well so no residue remains.
Squeegee technique: less product, more performance
Spray sparingly: an excess forces you to repeat the drying. Work from top to bottom and from left to right in slightly overlapping strips. With a rubber squeegee or a silicone glass cleaner, pull the water in continuous passes without lifting the tool. Dry the edge of the squeegee after each pass so it doesn’t drip onto what’s already clean. On small windows, a high-GSM microfiber cloth works just as well if you change sides often.
Streak-free finish on frames and corners
Corners retain moisture and create stains over time. Run a cotton swab or a fine cloth wrapped around a stick through the corners. For aluminum or PVC frames, use soapy water and dry immediately; on wooden frames, keep moisture to a minimum. A final trick: rub the glass with slightly crumpled newspaper to add shine, as long as the surface is almost dry.
Mistakes that ruin the result
Cleaning in direct sunlight causes the product to dry before removing the dirt. Using abrasive scouring pads or reused kitchen cloths with fabric softener residue leaves greasy films. And never mix bleach with vinegar: it produces irritating vapors. With a monthly routine and the right materials, cleaning glass stops being a frustrating chore.
