I've had my "use it all the time" piece soaking in 91% rubbing alcohol for about 24 hours. I'll scrub it with a tooth brush, and put it back together later tonight. I wouldn't say I enjoy cleaning it, but I do enjoy smoking out of a clean piece enough to clean it once every 2 weeks or so. My pipe also has a "resin trap", when I scrape it out, I get a nice little ball of resin, about the size of a 1/3 of a pencil eraser. I use it to pick up all the little bits of keif in my nugget jar... Just knead and stick, knead and stick... That little ball tastes like shit when you smoke it, but it gives a very nice buzz indeed! :bong:
