Here's what I do with my meers.... Immediately after smoking, I corkscrew a paper towel into the chamber, flip the paper towel inside out and do it again. Then I run a few pipe cleaners through the stem and into the shank. I wipe the pipe down with a microfiber cloth and return it to it's case. I do not clean my meers with alcohol like I do briars, I seen evidence on this forum of terrible discoloration in a meer because of alcohol. I do use it on the stem alone, but rarely. Other than that, I load them up and smoke them, sometimes multiple times a day, multiple days in a row.
