Here's a before and after picture of a meerschaum lined Italian pipe I picked up on E-Bay. I got it for a song and it cleaned up pretty nicely. Basically I sanded and polished the bit as well as sanded and restained the exterior of the pipe itself, followed by carnauba wax. The bowl was pretty cake-free so I just hit it with some 1200 grit sandpaper. I wasn't in the market for a meer lined pipe but I forgot to check a bid on a meer block pipe towards the end of the auction and consequently lost. Well, at that point my PAD wasn't satisfied so I quickly scoured the site for another possible purchase. This one caught my eye. So far I'm very pleased with it.
