Dawn Power Dissolver is slightly alkaline. Therefore it should not be left on the engine for two or three days or the engine boiled in a solution of Power Dissolver.
Power Dissolver usually does what it is going to do (cleaning with that application) within about 30 min.

I wiped my clean immediately, after getting the results I wanted. I never thought of leaving it for a long time in a solution of this liquid. Thanks for the tip.
