Once you have the ingredients, it will take you about 10 seconds to make this, the best window cleaner out there, and it will also cost you pennies. Maybe 1/2 a penny?

Around Earth Day 1990, many newspapers offered recipes for non-toxic cleaning advice, and the recipe for windows was just plain vinegar and water with the option of drying the windows with old newspapers.

The problem is, it didn’t work. The formula left streaks on their windows, and they swore off cleaning using kitchen cupboard ingredients because of it. What happened? The commercial products they had used for so many years had left a wax buildup and vinegar alone wouldn’t do the job of removing the residue. All the needed to have done to fix the problem was to add a dab of green liquid dish soap and the formula would have removed the wax buildup. After that just vinegar would work.

Here is the full DIY formula whether you have wax buildup or not. This makes two cups, enough for what, a year?

The Best Window Wash
1/4 cup vinegar
1/2 teaspoon liquid soap or detergent
2 cups of water
spray bottle.

Combine the ingredients in a spray bottle. Shake to blend and spray on your windows.
