Simple Green is a good cleaner/degreaser, nothing more. It's not going to suck any gunk outta your ball; for that, you need Hook-It.
Also, fell free to mix it 1-1 with water. It's plenty strong enough at that dilution to clean bowling balls. You can throw in a little rubbing alcohol too if it moves you, but it doesn't add anything to the effectiveness of the solution.
