In this video, I demonstrate using acid to dissolve limestone from petrified wood. This method works with any silica-type fossil, and is more effective at cleaning without damaging than using mechanical tools. If you are not sure what minerals a fossil contains, you should not fully immerse the fossil in an acid bath, or you will risk damaging it.

Time lapse video of using an acid bath to dissolve limestone aggregate from a piece of petrified wood. Unfortunately, while I took an "after" picture, I didn't take a "before" picture. I'll make sure to do that next time.

In my previous video, I found and dug up a large log of petrified wood. In this video, I clean it, and weigh it

In this video, I show digging up a giant log of petrified wood. In my next video, I clean it, so you can see what it actually looks like.
