Things You'll Need
Cleaning windows with baking soda makes them shiny and sparkling and removes any scuffs or stains on the glass. This homemade window cleaner has the added bonus of being non-toxic, with no harmful fumes or chemicals. Baking soda can be abrasive, so it's important to use it only on non-delicate, coated glass surfaces. Never use baking soda window cleaner on antique or stained glass as it could scratch or mar the windows' surfaces.

Hold a soft rag under warm running water. Then wring it out so that it is just barely damp. Sprinkle baking soda on the rag.
Wipe down the dry window with the baking soda side of the rag. Don't apply much pressure unless you're working on a scuffed area.
Hold a fresh rag under hot running water until it is soaked through. Use that rag to wash away the baking soda residue from the clean window. Dry the window with a rag or paper towel.
Repeat once weekly or as often as necessary. Make sure to keep an eye out for evidence of scratching on the glass surface of the window. If it appears cloudy or etched, discontinue use of the baking soda glass cleaner.
