So far, I haven't found anything that stuff won't clean. And it's cheap enough that you can afford to use it in large amounts if needed. I paid $16 a bottle for "Black Streak Remover" at the camper store and scrubbed my pudgy butt off and couldn't get the stuff to come off my camper. Awesome got sprayed on it and I stood there and watched the black streaks just run down the side of the camper without scrubbing at all. Great stuff for my money. Glad it worked for you. Ya always sort of worry when you suggest something to someone.
