While I'm boiling I scoop out my MLT with a big scooper since I can't dump mine. I found using a big sponge, like the one for washing a car works great for getting grain and liquid out of the bottom. I also use a hop spider to limit debri in the BK. After I get my MLT emptied, and I'm still boiling, I mix saniclean with water in the MLT and circulate it through my RIMs. After my beer is out of the BK, chilled, and in the carboy, I run the saniclean through my entire system. That's it, nothing special. I've never ran PBW through it, but am planning on doing it at some point. I do the same process before I brew too. Only takes 10 mins at the beginning of brewday.
