nobody has a clean enough microwave to give that a try. I don’t even have the courage to look at the roof of mine. i just wait for something to truly explode before i begrudgingly clean it. so yeah, the essence will permeate the purity of a clean moist cloth. anyway, I’ve often wondered if poe could take the place of 14 ga copper for doing primary lighting. also, my bro in law is building a new house with double cat to all locations just for a backup if one fails. doesn’t want to have to rerun wire. seems brilliant given its ease and low cost.
