Hello does anobody know how this product that is supposed to remove salt deposits from metals without affecting them works? It is butyric acid , hydrochloric acid and formaldehyde but I don't know the concentrations.

Probably vinegar or phosphoric acid.

What product? If there's a ref there I can't see it. Where did you get the mixture information? What is the stuff called? Asking such a question is like when someone asks a geologist, "what is this rock?" with no information on where it came from or what was near it.

It's called a descaler and it's sold by a chemist supplier. What do you mean phosphoric acid or vinegar? The ingredients are but-2-yne-1,4-diol
hydrogen chloride and formeldehyde not butyric acid , it's supposed to remove salt deposits from metals.

That mixture sounds dangerous
http://ces.iisc.ernet.in/energy/HC270799/HDL/ENV/enven/vol34...
"When exposed to HCl, formaldehyde forms the highly carcinogenic bis(chloromethyl)ether and catalyzes secondary amines to form carcinogenic nitrosamines/N-nitroso compounds."

Well 1,4-Butynediol is a corrosion inhibitor so that would stop HCL for oxidizing the metal I guess but why on earth would they put formaldehyde in there?
