I took up Pipe smoking a few weeks ago [and love it] and come to find out my brother-in-law did also when he was 16 for a week and still had the pipe.He gave it to me and after some research I found that it's a Yello-Bole brylon.It has very little cake but does have alot of tan...gunk?/oxidation?..throughout the entire pipe.Does anyone know the best/cheapest way to clean it?
