heat exchanger tubes.JPG
Anybody have any advise about cleaning out the insides of these heat exchanger tubes? They are 5/8id, so my jetting hose will fit but it won't make the turn down the ends. There is over 10,000 linear feet of tubing to clean so I want to get it right. Also, I'm assuming there is some scale buildup, so I'm curious if de-scaling acid is required or at least helpful.
