Hey Ol Thom I'm reconditioning some heat exchangers and someone
suggested soaking the tubestack in muratic acid to clean them
perfectly, they are all copper and solder and stainless on a oil heat
exchanger. Is that the way to go?


I can google better than Tom. I wonder if he can google at all on msmtv? Anyway here's
a link. It says using acid isn't a good idea. It says use sodium hydroxide instead...

Cheers,
