Use warm water with a squeeze of dish soap or a 1:10 white-vinegar mix, then squeegee and buff with microfiber for streak-free glass.
Best Things To Wash Outside Windows With
Great results start with simple mixes that rinse clean and don’t leave residue. Two standouts work on most exterior panes: a bucket of warm water with a teaspoon of mild dish soap, and a light vinegar solution for mineral film. Both pair well with a squeegee and a lint-free cloth. If your tap water leaves spots, switch to distilled water for the final rinse. That small change helps a lot in hard-water zones.
| Cleaner Mix | Ratio | Use Case |
|---|---|---|
| Dish Soap + Warm Water | ~1 tsp per 2 gal | General dirt, pollen, greasy smears |
| White Vinegar + Water | 1:10 | Mineral haze, light hard-water spotting |
| Plain Water (Distilled) | — | Spot-free final rinse on sunny days |
| Rubbing Alcohol Boost | 1–2 tbsp per quart | Stubborn smudges that resist soap |
| Oxygenated Cleaner (frames/screens) | Per label | Dirty screens and vinyl frames |
