+1 for PBW and no scrubbing. I take my chill water back to my mash tun, add PBW and then drain it into my kettle after the tun is cleaned. I'm not worried about sanitizing the hot side equipment at all. I do like to keep it clean however.
In 5 years I have used a cleaner once! I rinse and scrub it out with just water right after use. It gets almost all the crud out. I don't worry about the slight residue left. It adds flavor to the next batch.. 212F will take care of anything bad.
