How I pickled heavy rust on a large plate

[territorialmillworks]

I placed the plate on plastic, covered it with paper towels and gently wetted the towels with muriatic acid and covered it with more plastic. The plate was clean in 15 minutes. Appropriate PPE, good ventilation and a very small amount of acid used and then neutralized with backing soda.

Mods: didn't know were to put this........

 

We put in Alchemy, Formulas, Fluxes, etc for you.

I I had an old Vaughen linemans hammer head that had sat in a celar for no telling how long.  It was pretty much covered with dust. After soaking it in a jar of muriatic acid for an hour or so it came out clean as the day it was made.  As said earlier, good ventilation is a must.  I set mine outside by itself while I did something else.  Besides the fumes in your lungs are a bad thing, the fumes will rust most anything made of iron.
