i'm getting more efficient with my brew rig the more and more i brew with it, last time as my beer was in the BK i started to clean the HLT and mash tun.. my question is how good do you have to "clean" the HLT? is it worth soaking in oxy even though it has only ever held water? or should i just rinse it out before i use it next time and just use the oxy for my MLT?
