Our anode's threaded fitting and the threaded fitting of the tank have corroded so the anode hasn't been working (by the way, it's supposed to wear away - it's a sacrificial anode - and Teflon defeats it by insulating its the electrical connection. I can replace the anode to get new threads, but I'm wondering if I should get a tap/die to clean the opening threads. I started with CLR this evening, but I don't think it'll clean the threads sufficiently. Thoughts?
