Perhaps the single best way to get near, or original ball reaction is to extract the oil from the ball. Your ball's reactive surfaces turn on oil by absorbing oil as it rolls down the lane. This action increases friction and lets the ball do what it is designed to do.
Over time, oil will build up until the surface cannot react as it used to,
even if the ball appears dry.
The action of turning the ball over an absorbent pad under controlled heat for a couple hours will systematically remove all oil from the ball making the surface as it was when new.
