I dont remember its been a few years since I used it.It was what ever came with the unit & had like a 4 letter name like T.M.P.B. It didnt evaporate & etched all the oxidation off my wifes rings & necklaces & bearing grease sunk to the bottom in little balls.Go on line & look at I think integy or one of those types of companys,they used to seel a U.S cleaner & could probably see their recomendations.You could probably use naptha that stuff cleanes silicone & petolium oils off metal like right now & if pretty safe to work with I get that at home depot pretty cheap,they call it V.P.& M naptha.Not good for rubber but never had problems with plastics degrading in it.
