Re: [TCML] Cleaning Copper Primary Coil (with Muriatic/HydrochloricAcid)



Per Wikipedia: 

Concentrated hydrochloric acid (fuming hydrochloric acid) forms acidic mists. Both the mist and the solution have a corrosive effect on human tissue, with the potential to damage respiratory organs, eyes, skin, and intestines. 

The 20 baume' HCl that I've come across definitely meets the criteria.
