I just went through the difficult process of removing the foggy oxidation from a Charatan stem. What a pain in the ass!
On a sheer whim... while watching TV....I decided that the straight, very boring, stem needed a little more pizzazz, an ever-so-slight bend. So, I removed my fat butt out of the chair, boiled some water, stuck the stem into the hot water, waited for the Vulcanite to soften and then gave the stem some character. I was pleased when I looked at my handy work, but then noticed that the once, jet-black stem, now sported a foggy looking green-brown haze. Yech! So I rubbed the stem with toothpaste, buffed it with wax, soap, oil, and nothing happened.
Now, I was pissed! Fit to be tied!! I had no plans to sand away that greenish ghost, but I couldn't stand the look of the newly bent stem. I did it. I needed to correct it.
No mild abrasives, no buffing with waxes, worked. My last resort was to sand the stem with those micro-grit polishing pads. Now the stem is once again, jet-black....but I had to work too damn hard to reverse the damage.
Question: Once a stem is ghosted or lightly oxidized, is there any chemical solution, that can be applied that will reverse, and un-oxidize the oxidation, e.g. like a tarnish remover does for silver? I don't want to rub the discoloration away. I want to reverse the chemical action that caused it. Oils and waxes just coat the stem.
Just asking.
