I have two old mower wheels for a restoration but they are filthy. Years of ground in mud, grime and grease. Also the hubs have become very brittle. So I am wondering if anyone on this forum may have experience with cleaning up such parts? Should I just give them a long soak in detergent, or is there a better way to go about cleaning them? The wheels are hard to get so I do not want to ruin them. Generally I would just apply elbow grease but I don't want to damage the hubs any further. Any advice would be greatly appreciated.
