I've been accumulating a few estate pipes in various states of cleanliness. What is the bare minimum that one should do prior to smoking. I've been doing a light reaming, wiping down the outside, soaking and cleaning stems with oxyclean and using Everclear on a pipe cleaner to swab out the stem. I don't have a buffing wheel. I just want to limit the chance of catching some disease. What do ya think? Good enough?
