Can anyone recommend a good product to run through my AC units and circulation pump to descale them. I'm based in France and Northern Italy. Any suggestions??
Trac's "Barnacle Buster", phosphoric acid, in a pinch very diluted muratic acid. Oh, I guess I should have asked, are you talking about your raw water or fresh water (if you have chilled water) side of the system?
I use a product called Rydlime. I use this to flush various heat exchangers/condensors. I guess that folks out there have their preferences.
