Crusty beach button?

[tessmontana]

I've read a few ways on how to clean beach finds, would anyone be willing to give me some pointers?

I want to get the back of this button less crusty

Here it is next to a crusty threepence

Thanks Jaros, I had read the vinegar and salt method but didn't see any results so I was unsure.

I went ahead and did it

I busted the shank off

Every step you make or take you learn from.
