As far as deep cleaners go, Powerhouse Clean & Dull, and Neo-tac/Brunswick Hook-it are at the top of the list. Clean & Dull comes as a gel and Hook-it comes as a liquid, the latter has a strong grape like scent but both are very good. I've tried Powerhouse Energizer Cleaner, Power Wash, Lane Masters (strong chemical scent), Black Magic Rejuvenator, Tac Up, and currently Storm Reacta Clean. All very good cleaners that will get the job done but as far as deep cleaning goes, none are more widely accepted than Clean & Dull and Hook-it. Just remember after 60 games or so depending on how much you bowl, the ball will need a resurfacing to maintain the OOB reaction as close as possible.
