I was polishing the spud on an expander die the other night and noticed that the scratches don't really come out, they just get shinny. This makes me wonder if Mother's is an abrasive at all or just some kind of chemical polish with a wax. Clearly it is doing something more than turtle wax because of the blackened cloth. To my totally untrained eye it looks like some kind of chemical interaction perhaps striping off oxidation. Anyway,it made me curious and I thought I would ask.
