For those of us that do windows this is a great recipe!
1 small bottle alcohol
½ cup clear Ammonia
1 Tablespoon white vinegar
1 tablespoon Dawn Dish washing liquid
Mix ingredients in the order they are listed. This makes enough to fill a spray bottle and the rest can be stored in a gallon jug for use as the spray bottle needs refilling. This works great leaving windows streak free and is very cost effective too!
