Just wondering if any of you guys have had this happen to you? I only own one Ebonite ball currently, and it's a Savage that I use for heavy oil. This ball has been great for me when lanes were sloppy, or had heavy oil. It didn't move much, just gave me a consistent late, but hard break of a few boards, and would destroy the pocket. I usually played very tight lines with it, semi-direct.
  So anyway, I get the idea to drain the oil out of it. I soak it in hot, hot soapy water,(dish detergent), and out comes the oil. Lots of it. Suddenly the ball has new life!! Not only can I play the heavy oil, but I can use it in med-heavy as well. I can suddenly hook the whole lane. I can swing it. I can play down and in. Wow! A new weapon. Problem is......if I hit the pocket 9 times, 7 of those times I will get a ringing ten-pin, regardless of the angle to the pocket that I take. Holy Smoly, what have I done. This was the whole reason I stopped using Ebonite to begin with. Their balls didn't seem to fit my style, and I left way to many TEN_PINS!
  Guess I should've left it alone. Maybe I should only shoot inside lines?

If you happen to have read one other post, it said that using heat to drain oil would also drain some resin with it.  I think it had to do with coverstock death.  Basically, they have found that using any kind of heat, whether a dishwasher, bucket of hot water, an oven at a low setting, could pull some of the resin out of the ball.  So, obviously, less resin, less reaction.  I have found that using Hook It or Clean and Dull on a spinner after 6-9 games, will pull enough dirt and oil out of the ball in order to retain the ball reaction without pulling out the resin.  Thus, a longer lifespan of the coverstock and ball reaction.
