Why This Works So Well
| Element | How It Prevents Streaks |
|---|---|
| Vinegar | Dissolves minerals and grease; dries clear |
| Dish soap | Cuts through grime; prevents water from beading |
| Squeegee | Removes water completely; no drying spots |
| One direction | Prevents overlapping streaks |
The key is the squeegee. Most people rely on paper towels or rags, which leave lint and streaks behind. A squeegee removes all the water in a single, smooth motion.
Pro Tips for Perfect Results
| Tip | Why It Matters |
|---|---|
| Clean windows on a cloudy day | Sunlight dries the solution too quickly, leaving streaks |
| Use distilled water | Tap water contains minerals that can leave spots |
| Wipe the squeegee blade after each pass | Prevents dirt from being smeared back on |
| Work top to bottom | Prevents drips from running over clean areas |
| Use a microfiber cloth for edges | Lint-free and highly absorbent |
What About the Outside Windows?
Grandpa’s trick works just as well on exterior windows. For outside windows:
| Step | Action |
|---|---|
| 1 | Use an extension pole on your squeegee |
| 2 | Wash with the same vinegar-soap solution |
| 3 | Squeegee in the same top-to-bottom motion |
If there is heavy dirt or bird droppings, rinse the window with a hose first before applying the solution.
