One kind of weird thing I do is use my MLT to sanitize my pump and my chiller. After I start boiling, I immediately dump my spent grains and rinse out the MLT. I then fill it with a gallon or two of sanitizer and hook it up to my pump, then I recirculate Star San through it and the wort chiller, back into the MLT. People always think that I'm sanitizing my MLT for some dumb reason, but it's the one piece of other equipment I have that I can connect directly to the pump to be able to circulate through the chiller, and the MLT is a good size for tossing in all the other peripherals I need to sanitize. I just get everything circulating and let it go during the boil, then everything is all set to go when the boil is over - plus, the MLT is already clean and set to put away.
