I really like the diesel or mineral spirits flush- - - -that spinning crankshaft will do a much better job of cleaning the crankcase and the underside of the pistons, etc. than you'll ever be able to do with a brush. It's like an agitator in a washing machine. Drain the oil pan while the engine is still hot and a lot of the sludge will go with it.
