I agree, volley_man.
Given the price of a GALLON of SG, any EFFECTIVE mixture of SG, alcohol and water is going to be significantly cheaper than a good bowling ball specific cleaner. Given the price of them, I may yet try this mixture myself. I am not yet happy with a 50/50 mixture of SG and household alcohol (70%). When I feel so moved, I may try a a mixture of SG and 91% alcohol or even denatured alcohol, seeing as how it is now legal to use.
