So I tried cleaning my 2 510 atty's for the first time... I threw them in some boiling water for a while and dried them. One works like brand new and the other... well... it tastes like .... I don't know what happened, but it tastes worse than it did before! I took that atty and put it in some hydrogen peroxide, blew out the batt end, then even dunked it in some diet coca cola, blew out again, and then back into the boiling water, blew out, and dried. Still, .... Like burning turd. Is all lost on this?
