After reading a little about pipe cleaning after use, I decided to dip a few pipe cleaners in rubbing alcohol and run them through my pipe. It was cold, so I pulled them stem off, and the inside parts a good wipe down with the alcohol soaked cleaner. A few drops got on the black stem, so I thought I'd give it a wipe too. Seconds later, as I was wiping off the stem, I noticed to my horror that it'd changed colors a little, it's now a dull black instead of shiny like it was before. Have I done something horrible here, or is there some way to bring back the shine?
