You are talking about Petersons, right? When I got my Rua, I was going to rinse it out before smoking it, like I've done over 100 other pipes I've bought, with not a single problem. But, one good and one bad thing happened. The good was that the bowl coating just whisked away easily. The bad was that my hands turned red from whatever stain Peterson uses. That was the first ever time this happened.Because it removes stain and damages many pipes’ exterior. Same way water doesn’t penetrate the wood, neither does the stain so it’s often readily removed by some water.
It totally lost that beautiful contrast of red and black, but.... phhhhht, so what., I just buffed it up with carnauba wax, and ran water over it again, no problem. It's just red now. Cheap pipes... what would I expect. I understand that Bringham pipes uses a cheap stain also.
