1/2 gallon warm water
1 Tablespoon of liquid "Jet Dry"
2-3 Tablespoons of liquid laundry detergent or dish washing soap
Mix all of the ingredients above. Spray your windows down with your hose to get them wet then wipe or brush on the solution onto your windows, then immediately hose it off. That’s all there is to it and you're done. The remaining water just sheets off and you don't need to dry it off!
