I weighed my oldest TBAC Ultra 7, it weighed damn near 14 oz's...I have been giving it frequent CLR baths all week long. I noticed it doesn't take the CLR very long to work at all, I just think I have so much shit in there it kind of turns it into a sludge like material that is difficult to get out.
Anyone trying using an air compressor with a discharge nozzle to knock all the sludge loose? I am making pretty slow headway, about .05 oz a day...
Same thing that mine did. Had to completely soak in on CLR for about 24 hours to finally get it knocked loose. If you have an ultra sonic cleaner, run it through a few cycles of that with Simple green in it after the CLR soak. I’m not sure what kind of nozzle you’re talking about but did blow it out with my compressor and it helped a little with the last little bit of loose stuff.
