The white in the Jigsaw did not attract the dirt. It is not a magnet for dirt. It only allows you to see the dirt that is ALWAYS on the lanes where you bowl. If you think your black ball did not pick up that dirt, boy! are you wrong. The dirt is there and your balls, along with everyone else''s who bowls there, are picking it up.
If Clean and Dull cannot remove the dirt, it has been ground into and scratched into the resin.
Acetone will not remove the dirt. It will partially dissolve the resin into which the dirt has been ground. It will look "pretty" once again, but you will have slightly changed the surface. I would not recommend using acetone JUST to make the ball look pretty again.
An occasional swipe with acetone will not harm the ball. Using acetone to remove glue or really bad rubber marks from broken down belts is fine, as far as I am concerned. Constant rubbing with acetone will make larger changes to the ball''s surface. Not immediately, but over time this will have a cumulative effect. This is why the basic test by the ABC/USBC is laying a soaked cloth on the ball for 15 - 30 minutes.
