M-II's revolutionary Laundry Ball allows you to eliminate your regular soap, chemicals, and softners on regular loads. Add one ounce regular soap to heavy loads and one ounce of Neutralizer to smelly loads. Add 1/2 cup of vinegar to whites as well as above where applicable. The ball will last indefinately if you don't allow the kids to play baseball with it, dog to think it's a toy, and or accidently throw in dryer...etc. :-) Specify color preference: blue, orange, red, green, or yellow.
