I have cleaned estate pipes before. A few that I couldn't even get a cleaner through the stem when I first started. So obviously a few years of grime and neglect. Various odors from good to not so good, but never in my life have I ever smelled peanut butter while cleaning an estate pipe. Salts, bleach, Jim Beam and PEANUT BUTTER. Two questions- Do you think the previous owner smoke a peanut butter blend by Reese's??? What other funky smells have others experienced?
