Bar Keepers Friend.

I LOVE this stuff. If you are looking for a good cleaner for your flat top stove, sink, counters, and even toilets.... it is for YOU! With this and a sponge (one with the scrubber on one side), you can attack anything. I promise. It is super cheap and it works awesome. I suggest wearing gloves because it can leave your hands feeling a bit funny and "dry" but even then, it is totally worth cleaning with. You can find it by the Comet, Ajax and other cleaners at a store near you! (do I sound like a commerical?!) Yeah, go get some if you are looking for something cheap to clean with. It ROCKS!
