You can go to Dollar Tree and buy their organic cleaner also, or the 99 cents only stores. They work just as good and don't hurt anything just don't spray it right into your bearings and make sure you shoot the bearings with WD-40 or kalgard 30/30 after you dry it. I've been using cheap alternatives for cleaners for a year now and have the same success as I did with Simple Green for allot less money.
