Screw that water-based degreaser! Petoleum-based works one helluva lot better. I'm not going to be exposing my skin to it because I'm going to be wearing triple-layer rubber gloves, and I don't intend to spill it. Unlike water-based cleaners, you can use petroleum-based cleaner forever by simply decanting the liquid off the accumulated solids. Water based cleaners actually create more pollution because you have to dispose of them when they become ineffective.

But if you really believe that stuff, RRR, then our California Governor Jerry Brown has a position open in the state's Department of Environmental Protection, and I think you should apply for it.
