Some facts from Cougartron:
Sleeved carbon fibre brush soaked in 50-ish % phosphoric acid solutiom, hooked up to a +30A, 18-12V (assumed DC?) PSU.
Neutralize treated area w 5% sodium bicarbonate solution (baking soda),
as pure water rinse just won't cut it - some staining might then appear after drying.
They claim 1.3 gal of their weaker, 10-25-ish% acid will last some 5000 ft of SS TIG weld.

So - who'll be the first picking up this challenge and hooking their Computer Server PSU
(see pics: Just been lying around for a few years...) up to a DIYed Magic Wand?
I won't, as I wouldn't touch a TIG - we have a junior "Intersectionality aware" personality excellent at TIG welding
(also at critical race & gender theory) at my Uni's shop.
The verdict: "-Water-damaged phosphoros acid is for WIMPS, man!"
