If you must use Neo-Tac, use either Hook-it (VERY powerful) or their Nitro. Both are good cleaners.
I'd avoid using Renew-it ONLY because it's also a polish. If you have a dull ball, it will get polished. If you have a polished ball, it can get more polished than you need or want.
I'm a believer in - if you want a cleaner, use a cleaner. If you want a polish, use a polish.
