This is one of those valuable ‘Hints from Heloise’ that has been passed down from generation to generation. It not only works great, but is money-saving as well.

HOMEMADE WINDOW WASHING RECIPE
Mix 1/2 cup nonsudsing ammonia with 1/2 cup rubbing alcohol and 1 tsp. dishwashing liquid with enough water to make 1 gallon of cleaner. Put in a clearly marked spray bottle. Drying with crumpled-up newspaper will give you a streak-free window too.
I also saw this recipe in my good blogging friend Lark's cookbook, so I'm sharing it also. Maybe you have these ingredients on hand instead...
OUTDOOR WINDOW CLEANER
1/2 gal. warm water
2 - 3 Tb. (liquid) laundry or dishwasher detergent
1 Tb. liquid Jet Dry or other dishwasher wetting agent
Mix ingredients. Brush or sponge on window. Immediately hose off. Water will sheet off. No drying necessary. (sounds like my kind of work!)
CAUTION: Be sure windows are tightly closed! :-}
