Trac Ecological Barnacle Buster

I had a generator heat exchanger that had some really bad scaling, 50% clogged and most the other tubes were still pretty bad. I was just going to buy a new one when I saw this stuff and thought it was worth the risk/cost, given what even a small heat exchanger costs. I soak it and it starting foaming Immediately, I had to move everything to a deeper bucket, one lessoned learned, now shared. Still leery I pulled it for a checked after about an hour and was like ""holly %^&"", couldn't believe it, the partially clogged tubed were spotless, it was working its way through the full clogged tubes. After about two hours it looked like a new heat exchanger, I was dumb founded. Also can't believe how much more water is coming out of the exhaust, worried it may never get hot enough now! LOL As a result I recently built a bucket flush system for the big mains. Although I am not pulling these heat exchangers out I did pull the hoses and shine a flash light in there, and they look a lot cleaner than before. Gave it 4 because it is pricey, to flush any big motor you do need gallons, but is a lot safer then muriatic acid.

I purchased the concentrate and it was easy to mix and use. Just remember to flush out your pump with plenty of fresh water after use. I ran the engine afterwards, so it flushed itself, but I left it in the pump and the plastic vane impeller disintegrated.
