This glass cleaner works well. It gets the job done. It is a lot cheaper than even the cheapest window cleaner out there. Is it my absolute favorite? No, but it does a good job and again, I can let the kids help!
The Best Window Wash
1/4 to 1/2 teaspoon vegetable-oil-based liquid soap (for this I use my Seventh Generation Dish Soap)
3 tablespoons vinegar
2 cups water (I use warm tap water)
Just put all the ingredients into the spray bottle, shake it up a bit, and use as you would any window cleaner!
You can leave the solution in the bottle. It does not need to be made new each time.
