I have one of those chain cleaner things in which you're supposed to pour a cleaner/degreaser, then backpedal your chain through it. I was wondering if anyone has tried Simple Green for this, and if they could tell me how well it worked.

The reason I am asking is because I have a gallon of it sitting here, and I figured it would be silly to go out and buy something else. Otherwise, if Simple Green is not a good suggestion, can anyone recommend a good eco-friendly degreaser?

Thanks.
