What are you using in yours? I want something relatively safe. I don't want anything that eats skin, ruins clothes, disolves plastic, stinks up the whole garage, catches on fire, explodes, You get the idea. At the same time it would be good if it actually removed dirt and grease LOL. Is there such a product? Does it cost an arm and a leg?

Thanks

In theory, there is no difference between theory and practice. In practice, there is.
