Simple Homemade Glass Cleaner with White Vinegar and Mild Washing-Up Liquid

A homemade glass cleaner made with warm water, white vinegar and a tiny amount of mild washing-up liquid helps lift grease, fingerprints and light mineral residue. To avoid streaks on windows, mirrors and the shower screen, though, the cloth you choose, how much you spray and the way you dry are just as important as the mixture itself.

Why do vinegar and washing-up liquid help to clean glass?

White vinegar contains acetic acid, which helps loosen marks left by water and light mineral build-up. That mild acidity also makes it easier to remove residue that stays on the glass after rain droplets or shower splashes evaporate.

Mild washing-up liquid works on the grease found in fingerprints, kitchen vapour and body-care products that collect on the shower screen. One drop is enough to support the clean, because too much creates foam and leaves a film that can show up as a halo once the surface dries.

How do you prepare the homemade glass cleaner in the right ratio?

You can make the formula in a clean spray bottle by combining equal parts warm water and vinegar. Mix only what you expect to use soon, rather than leaving the solution sitting in the bottle for long periods:

• Pour 250 ml of warm water into the bottle;
• Add 250 ml of white vinegar (spirit vinegar);
• Add just one drop of mild washing-up liquid;
• Close the bottle and combine with gentle movements;
• Label the container and keep it out of children’s reach;
• Never mix the solution with bleach or other cleaners.

Why does the glass still look streaky after cleaning?

Many marks appear when the product dries before it has been spread and removed. This is common on windows warmed by the sun, because the water and vinegar evaporate quickly and leave visible lines before the glass is polished.

What you use to wipe also affects the finish. Cotton cloths, worn flannels and kitchen roll can shed fibres, while applying too much product leaves the surface soaked. A clean microfibre cloth absorbs the solution more effectively and reduces the residue that causes streaking.

How do you use the mixture on windows, mirrors and the shower screen?

Before you start, remove dust and loose particles so you do not drag grit across the surface. Spray only a small amount of solution and wipe it away promptly, using the right approach for each area:

• On windows, wipe with microfibre and finish with a squeegee from top to bottom;
• On mirrors, spray the cloth to prevent liquid pooling around the edges;
• On the shower screen, let it sit for a few minutes on light mineral marks;
• Dry the squeegee blade after each pass;
• Use a separate dry cloth to buff corners and trims;
• Clean when the glass is cool and out of direct sun.

Correct drying completes the clean without streaks

Move the squeegee across the glass in continuous strips, starting at the top. Wiping the blade between passes stops dirty water from being spread back over the surface, while a dry microfibre cloth lifts droplets left around the edges and where the glass meets the frames.

This method for leaving windows clear works best with minimal washing-up liquid, moderate spraying and immediate buffing. With the homemade glass cleaner used on a cool surface, the combination removes grease and residue without creating the film responsible for halos after drying.
