I am seeing some rust at the base of my HLT electrical element. I don't keep water in the tank. Only when I brew I keep water in it and usually that lasts 4-5 hours.
I understand that if I install a galvanic anode(preferable magnesium) but I don't want to drill the keg, can I put it at the bottom of the keg ? I don't see why.
Also can I use starsan to cure the base after I clean the run of the base of the element ?
Lastly just a silly question, can use oil to coat the base then turn the element on for 5 seconds (not submersed) the idea being that the oil will burn leaving behind a carbon layer process used on cast iron pots.
