[TheForge] Spring steel (and other) breaking in mild acid

[Clyde Wynia]

Thanks for the answers, no solutions, but some good thoughts. I was hoping
for an easy solution to this breaking, like just dissolve a couple of
aspirin in the acid mix. I will just sand blast the springs from now on.

Would that be sufficient to cleve used tool steel with a mild acid?
Not talking about just added embrittlement.
Always wondered about the steel tanks containing pressurized  hydrogen too.
Familiar with it in welding.
