Wow, Bob,I thought this was going to turn into a name calling match about you two's lineage real quick!!

I haven't used Mother polish but have added whatever liquid car wax is on hand for years. I have never clened it post cleaning and have had no issues. A lot of the time now, I'll toss my loaded rifle rounds in the cleNer for a little bit to remove the sizing lube and give it one last clean up. Can't say I've ever had any buildup or other issue due to the wax coating the loaded rounds. They sure do look pretty, though!.

Might be my imagination, but I think sizing afterwards is easier.

It also seems to help prevent the brass from re-tarnishing longer than regular polishing media.

Only thing to watch is not to add to much to the media - it will only absorb so much. Luckily, if that happens, just mix in more untreated media.
