I was passing through Arizona on I-40, and took a slight detour to collect at Dobell ranch. Does anyone know of a way or have suggestions to clean the whitish crud off of the specimens? At first glance, it just looks like dirt that would rise off, but doesn't. It's somewhat consolidated, but still pretty soft and grainy. Maybe limestone that has not completely set up yet?

If it is not too thick of a "rind", I have used Lime A Way in a little tub and let the rock soak for a few days. That works for the tumbling sized smalls, but not so much on the 100#ers!

I used muriatic (pool) acid on the wood I got from Dobell's a few years back. Three parts water to 1 part acid. Use rubber gloves or tongs. Should do it. Lime A Way works too. Not as fast as the acid but that's ok.

Thanks for the quick replies. I’ll get some of one of those.
