Milenko -- For a routine cleaner, I use a mixture of 1/3 Simple Green, 1/3 rubbing alcohol, and 1/3 water. I keep it in a spray bottle and use it with my spinner, but it should work just as well by hand. The Simple Green cuts the oil and the alcohol gets belt marks and "lane dirt". After cleaning, I use a wet paper towel to remove the residual cleaner before drying, otherwise it leaves a film on the ball. Cheap and effective. -- JohnP
