I'm talking about pipes. You clean your pipe after each smoke very meticulously using several pipe cleaners and pipe sweetener getting it ready for the next time, giving it a couple of days off. You revisit that pipe and your tobacco tastes bland, no distinctive taste difference at all between the other blends you enjoy. I was begining to think my taste buds were getting fried. Then one day I could smell my pipes from across the room as they sat in the rack. I had P.O., the dredded "pipe odor". I ordered some Pipemaster's Clean & Cure recently with one of my tobacco orders and it made a significant difference in the taste of my tobacco after using it. This stuff works great compared to the other sweetener I was using. I smoke a pipe to enjoy a variety of different tobaccos. When everything tastes the same it gets boring and disappointing. Sour bowls are no fun. Is there anything you guys do differently to keep your pipes fresh?
