The Pushrod Cleaning Brush from Goodson has tapered bristles to make cleaning pushrods with an ID down to .080" easy. The brush also measures 12" long to fit most pushrods. It's important to clean the insides of your pushrods when rebuilding an engine, because not cleaning the ID of the pushrods risks contaminating the engine. A hot tank often cannot get the gunk and sludge off the pushrods.
