I’ve been dealing with my collection which is mostly estates and realizing that some pipes, even after hours and hours of sanding and polishing still have bits of oxidation I can not get rid of. Some of them have oxidation just inside the button. It seems I can never get it all and this is frustrating me. Should I give up expecting it all to be gone and accept there’s always going to be a little? I have no power tools, BTW.

I don't use power tools and all of the stems that I've burned the oxidation off of haven't re-oxidized.

Remove oxidation and then keep them pilished and oiled regularly. Keeping sunlight off them aids as well. Once it is under control, it is possible to stay ahead of the game, but you do need to keep them oiled and polished. James Upshall and Charatans are the absolute worst it seems.

How do you know it is actually oxidation? I’m not a chemist or materials scientist, but I’d love it if one chimed in here.

I do know that modern rubber compounds are much better than old ones. Rubber making was often a seat-of-the-pants operation, and that sometimes resulted in less-than perfect formulations.

My solution is to not worry about gray/green stems, and to simply re-dye them if they look cruddy.

I singe the oxidation working in small sections at a time with the tip of a lighter flame and then wipe away the blackened areas with a wet paper towel. I return the shine by thumb buffing with toothpaste to a mirror finish.

Amazing job, i just went back and read your other posts on this and the videos you linked, I have two P Holm estates and the stems aren't horrible but i did one with wet sanding and working up to a super fine grit then microfiber to a "shine" .. the other one I'm going to do with flame, if i eff up at least the stems are interchangeable ... One Stem, Two Bowls... could be the new interest sensation ROFL

Getting oxidation out of the space just inside the bit is a nightmare. Yes, I’ve begun oiling after every use and covering/storing. I bit into my Dunhill where it had oxidized and left a mark and now I can’t buff it out as hard as I try and there’s a little tin-tiny spot of oxidation. Maybe I’ll try burning it but I’m afraid.

Which suggests that the rubber formulation had too much sulfur in it. It doesn’t necessarily mean that it is oxidized. Saliva and hot water cause the same reaction.
Just as oxidation with metal, moisture causing rust. Steam will flash oxidize vulcanite.
