No matter what you use for an anode, keep in mind that the surface of the workpiece facing the anode gets cleaned the most. That's why a cylinder or tank as the anode, with the part inside of it, works well. Or for cleaning the rusty inside of something, hang the thing in a bucket and put your anode down inside it. I've got a tube bent to fit inside a thermostat housing, for example, to de-rust the inside of it. If the part itself will hold water, it can be the "tank" and the anode can hang down inside of it. Since you can't over-clean the part using this method (unlike an acid pickle), you can get away with a fairly inefficient setup if you just let it run for a long time, but it will take approximately forever to clean the side of a part that's facing away from the anode, or the inside of something where the anode is outside. In general, whatever you use try to put some of it on all sides of the part. Either that or figure on just cleaning it one side at a time, and turning it around until it's done.
