I've spent the last 24 hours doing acid... on some of my my old Honda's chrome.
I filled a bucket with hot water and added about 1 Kg, mixed it then poured into a handy big plastic bin.
I did the front wheel, 60 degrees at a time:
And today, the front mudguard:

Whatwas the composition of your salt bath and how did you heat it if you don't mind me asking?

24 hrs in citric and the bolts are still fizzing away. Appear to have white crystals on some:
Emptied half the solution out and gave a good shake. Then rinsed in hot water / Fairy:
No longer red rust but still cruddy in the threads. After cleaning the threads:
Seriously, is it worth it?

I think you need to up the conc. there. They should be nice grey steel in an hour or so.
Well pleased with my mudguard. Gave it some more, over night.
That was done in approx. 100g/L and the mix still has life left in it - the little Record plane only needed an hour.

Yep, I didn't use the usual 1:4 / 1:19 powder to water ratio I usually use.
Will citric avoid me having to use a slitting disc? I will find out on Wednesday.
The 1979 Honda's centre stand pivot is (commonly) seized, ceasing proper operation.
Left in this state, eventually the frame's mounting holes go ovoid and it gets all sloppy down there.

Good question; I believe that citric does get between particles of rust and help 'soften them up' even before much dissolution occurs.
You might consider adding some IPA (10%) to the citric solution which would act as a wetting agent and help the solution penetrate. If you don't have any alcohol, a drop of detergent would probably help.
Most detergents are alkaline so will neutralize the acid!

Most detergents are pH neutral?

Alkaline, as far as I know. It's only ones for sensitive skin which are neutral-ish?

Afaik,
Bleach is an extreme alkaline, hence it's killing bacteria being very efficient.
The opposite of a strong acid.
