Washing IBC totes? I've seen here a couple times hot water is the key. Right now my outdoor hose is on a valve splitter to my cold laundry supply, so switch it to the hot line for this? Hot water tank is 40 gal, WWW brings our water to our house 425 gallons at a time and it's kind of a pita so I'd like to do a thorough job but not waste water, kwim? Probably the weekend after next. Whats recommended?, on hand I have dawn dish detergent, tsp, borax, oxiclean, bleach, gel dishwasher detergent, or is there something I should buy? I can see getting the bottom 2/3 with the spray wand, how do I clean the upper 1/3?
