Howdy Folks: this hho experimenter has been running KOH for maybe a month now and I'm still getting the dang brown bloom that I had with NaOH. I can drain off to a degree, but I don't like it at all for show and tell...
and when time comes for cleaning my neutral plates, it will be a pain. I've used vinegar... anybody out there using citric acid, or maybe potassium citrate??
