I've dipped a fossil piece into diluted acetic acid and removed it after an hour. It's currently sat in water, but's in the short time it' been in there it's developed lots of salt crystals on the surface. How should I remove these? Wait until it dries and use Acetone? Thanks.

I have some Limestones full of fossil including fish teeth. Traveling all over our small home town to find the strongest "vinegar" I could, and first I saw a gallon at the supermarket was 5%. Pickling vinegar at Walmart - 5%. Cleaning vinegar at Home depot - 6%. They advertise on their web site 30% called "Ultra Vinegar" but no one in the store has a clue. Ive heard that 10% is what is used on the Gogo stuff. Please give me your thoughts, thanks!

Hello, Long time occasional lurker, first time poster; I hope this is the appropriate place and method for posing this question, and I apologize if it is not! I have some limestone blocks containing conodont teeth and shark teeth, which I would like to break down with acetic acid. From what I have read, adding a buffer to the acid solution would greatly help in preventing damage to the teeth (and especially the roots), but I have no idea what buffers are readily available (and from where they would be available) and commonly used (and how much is needed). Can anyone advise? Any experience you've had with buffering acetic acid for dissolving limestone matrix to retrieve small teeth that you'd be willing to share would be greatly appreciated! Much thanks! :-)
