Many store-bought window cleaners have labels that list hard-to-pronounce chemicals as ingredients, but you don’t need that stuff to keep your glass clean. You can save a little money by making your own window cleaner.
Window and door seller Jeld-Wen offers an astoundingly simple formula for making the cleaner. You start with a a gallon of water, to which you’ll add either a teaspoon of baby shampoo or a cup and a half of vinegar.
To use the cleaner, swab your window clean with a cloth or sponge dipped in the solution, then rinse with water and dry with another cloth. If the process works well for you, that’s one less cleaning product you’ll have to stuff in your cabinets.
