Sup guys, was looking for some advice on how to polish the 510 ring on my Prax1s v2. Never felt the need to polish my brass on mechs or rda's and so I dont really know which direction to go. Got a pic down below (not my picture) of what the ring looks like. What should I use to clean it? Was told to use Mother's polish but when I googled "Mother's Polish" I found their other products as well and didn't know which one I needed lol Help me out please! Any other polishing methods or products would be cool too, all advice is appreciated 
(mines not a clone btw lol wouldnt bother polishing it if it was)
