Achieving streak-free windows is a hallmark of professional cleaning, especially on heavily soiled surfaces from heating residue or urban pollution.
In my years of hands-on window cleaning experience, I've perfected a simple, eco-friendly homemade solution that delivers impeccable results without wasting a full day.
This trusted recipe combines 70% rubbing alcohol and a touch of dish soap for pro-level performance at virtually no cost.
- 70 ml of 70% rubbing alcohol
- 4 tablespoons of dishwashing liquid
- 4 liters of hot water
- Basin
- Sponge
- Clean cloth
- Squeegee
1. Mix all ingredients in the basin.
2. Dip the sponge into the solution.
3. Wipe the sponge across the windows.
4. Focus on the grimiest spots.
5. Scrape with the squeegee.
6. Buff edges and corners with the cloth.
Perfect! Your windows gleam streak-free, even in direct sunlight.
Quick, effective, and hassle-free—no more hazy glass or lingering streaks.
This economical mix stores for weeks and works great in a spray bottle for convenience.
Prefer no cloths? Crumple newspaper for that final polish.
Work on overcast days to avoid glare and spot dirt easily.
For extra-grimy windows or rain spots, pre-wipe with the solution, rinse the sponge, and repeat before squeegeeing.
70% rubbing alcohol cuts grease powerfully and evaporates cleanly, leaving no residue. Dish soap and hot water amplify the degreasing action for flawless results.
