I found this on another site and I believe this is the most common one.I have never used it but did hear you need to wait the week to let the peroxide work off. In Georgia the wind blows from four directions every hour.
"Mix 16 oz distilled water, 16 oz peroxide, 1/4 cup baking soda, and 1 oz of a fall blend scent killer shampoo or laundry detergent together. Let it stand in a gallon jug with the top LOOSELY on for about a week. Stuff works great."
