I was talking to Del Warren awhile back about ball care, and he told me that getting the oil out of the ball was highly overrated...the lane doesn't know that there is oil embedded in the ball.
The real issue, he said, is dirt clogging up the pores of the balls and not the oil at all.
Now, I know it's his job to sell Track stuff, but I did buy some Clean & Dull and Reaction Plus and they did seem to do a good job for me. Maybe we take the oil-removal too seriously, and should concentrate on the part of the ball that actually contacts the lane.
