I like to keep my pipes in pretty good shape, but I'm not insanely meticulous about them. About once a month I'll give them a nice outer cleaning and stem polishing. As for the internals, I only take them apart for a deep cleaning as I feel is needed, i.e. the pipe stops smoking sweet or smooth. I always run a pipe cleaner (or two) through the stem, and twist a U-shaped pipe cleaner into the bowl after each smoke as well as wipe the stem down with my shirt. I try my best not to drop or ding them, but it happens. I always carry my pipes in a pipe pouch, never in my pocket! Like I said, I'm not quite OCD about my pipes, but I like for them to be in fairly nice condition.
