Circular motion to begin with.
If you're trying to do away with paper towels (see How To Go Paper Towel-Less in the Kitchen) while minimizing your laundry but still need to clean your windows, consider using newspaper. Not only does it work really well, the paper and ink acts as a light abrasive to give you really clean windows.
What You Need
- A dirty window
- Window Spray or Vinegar & water (If streaks persist with just vinegar and water, try this recipe: 2 cups water, 1/4 cup vinegar, 1/2 teaspoon liquid soap) See also Best Green Cleaning Products 2009
1. Collect Your Materials
If using a window spray, this part should be easy. I choose Mrs. Meyers Clean Day Window Spray because it smells so good and is mostly natural. If you're trying vinegar, dilute with water. A good recipe is 2 cups water, 1/4 cup vinegar, and 1/2 liquid soap (to get rid of the waxy film that might be on the window).
2. Apply the Cleaner
A squirt bottle works best but you could also lightly dip your newspaper into a jar of cleaning solution if needed.
3. Rub to Clean
Begin in a circular pattern to wipe off all the spots. Then, switch to a vertical, and then horizontal stroke until all the liquid has dissipated and you're left with a shinny, streak free windows!
Note: for vinyl windows, I've found that the newsprint leaves a mark on the white frame. Avoid rubbing the window frame with newspaper and stick to the glass.
