Keg surface rust

Postby davesims » Tue Jun 12, 2018 1:32 pm

Hi all

My brother in law has a stainless keg turned into a boiler, he has noticed he has a little surface rust inside on the bottom of the keg

What is the best way to remove this?

I'm sure there's a thread here somewhere about passivation of rust. Maybe search "passivation" see what comes up?

Cheers,

I’m no Boiley but the bloke who tigged up my boiler additions finished off with a ss pickling paste, perhaps that will help?

It would.
Playing with it should be done with extreme caution and full PPE, it is nasty stuff.
Essentially nitric and sulphamic acid or hydrofluric acid.
Either way dont get it on your skin as it dissolves bone.

Vinegar is safer and will do a bit for your issue.

:text-+1: yeap, he described it to me and was very cautious, so if you do use it yourself follow the sds and advice from BOC or wherever you buy it from.
