Hey, we're all newbies some ways, right? Might not be new to the pipe but this is a "newby" question I suppose. Basically....why, appart from aesthetics, should I give two squirrel farts about rim darkening? I have some level of darkening apparent on all of my bowls pretty much. Is there a good way to remove it? I ask for vanity's sake. Is there a good way to prevent it? I don't intentionally ever hold flame over the rims, I try to be careful, but it seems I inevitably end up with some darkening. In the long run, is this in any way harmful to the pipe from a functional standpoint, or does it just look less beautiful than a pipe without it?
