A mixture of one part vinegar and one part water in a spray bottle works great. If you need something a little more powerful, I've heard that Bar Keepers Friend is THE BEST, for cleaning. I've never used it but I understand people swear by this stuff.

Here's a list of things you can try. I usually use a germicidal foaming cleanser that I have tons of lying around someone was getting rid of but I've used vinegar with olive oil with success.
