Does anybody here really believe bowling ball manufacturers are going to dedicate research and development dollars to ball cleaners ? It's reasonable to assume they take chemical properties of household cleaners and combine them with some scents and, voila. Seriously, simple green & rubbing alcohol citrus based cleaner & rubbing alcohol, windex, etc. whatever works - works. But to decide for yourself, clean your balls with any of the above, then use a bowling ball co.'s cleaner with a clean towel and see if you get more dirt off the ball. If you did, then it's a better cleaner than the household one. I'm sure some household cleaners are better than some bowling co.'s cleaners and vice-versa. But don't use harsh chemicals that may harm your ball (e.g., acetone, thinners, retarders, etc.), and whatever you do, don't mix bleach and ammonia.
