Shiny Lil Detlr said:Try Castrol Super Clean or Meguiar's Super D-Greaser... I've never had bad luck with either of those.
I wouldn't abandon the idea of a steamer altogether though... I use mine a TON, even in conjunction with the other chemicals, and not just on the engine.
Thanks-just ordered Meguiar's Super Degreaser. I'll try that next time.
