6 /12 cups of water
1 cup rubbing alcohol
1/2 cup household cleaner (I use Mrs. Bonner's magic soap, my sister introduced me to it and I love it. You can get it at health food stores)
Stir all together and spray daily after you shower.
It makes 8 cups.
The final product fits perfectly into a 40 oz. spray bottle with a quart left for later.
