Some of the more aggressive coverstocks will come OOB with a white haze. (Brunswick Scorchin' Inferno, Columbia Power Swing, Roto Grip Epic Quest, Track Mean Machine, etc.)
This white haze disappears as soon as the ball sees a little lane oil and gets wiped down a few times. Some shop owners will put a little polish or even oil on these more aggressive balls to increase the shelf appeal of the ball.
If you give one of these balls a thorough cleaning in a dishwasher or some other method that gets out most of the oil, sometimes the white haze will return. Try throwing it a few times and wipe it down with a towel. I'm willing to bet it has its reaction back and the white haze goes away pretty quickly.
