As a hobby I like to restore old briar pipes....to smoke not to sell on. I've recently purchased two rare and much sought after London made pipes off of Mercado Libre which were going for a song. Most pipe restorers use a Magic Eraser to get rid of the years of grime and carbon that can build up on vintage pipes.
I'd never heard of such a thing but seems they are commonly found in the US and Europe. I had a look on ML but nothing found. Does anyone know if they sell a similar item here?
