-----Boiler cleaning with oxalic acid
2005
A boiler needs cleaning. The boiler is now operating and is corrosive. So not much scale attached. the main deposit is Iron oxide, and the Boiler is still corrosive by oxygen (no Tannin or Sulfite is used)
In such case, Boiler acid cleaning before applying oxygen scavenger is nessecary? The acid can "sweep out" scale and cause more severe corrosion after that? I intend to used 3%
oxalic acid

eBay or
Amazon [affil link]
and inhibitor to soak the boiler (small boiler) for 6 hours. Oxalic acid seems not much applied in Boiler cleaning, So I wonder is it OK. The reason of oxalic selection is its capability to de-rust of oxalic acid.
Thank you very much

Oxalic acid is toxic, much better and cheaper choice is citric acid ⇦ on eBay or Amazon [affil link] . Good luck!
