One very minor PITA with these brew buckets is to get the stainless steel muck off the inside, take a wet paper towel and scrub a small surface several times hard and you will get steel sediment. So To save you time i have tried it all, from all sanitizers to denatured alcohol, paint thinners, laquer thinner, acetone..etc... Then finally tried Naptha (do it outside)! Then only a couple swipes to get it removed.
Another thing I did was add a thermometer about 3" above the drain spout. Drilled a 1/2" hole with a titanium step drill and installed a blichmann thermometer. Carboy heater on them at 67 and all is going good.
Not sure what to do with the carboys.
