I have a few nice Dugway geodes- but some have a clay like light brown stain on the quartz crystals-the same kind of stain found on the outside of the geodes
any suggestions on cleaning?

You might try Iron-out. I've used pool muriatic acid too but it's more dangerous to use.

I've seen a video of a guy soaking them in oxalic acid or could have been what suggested by Sabre52 then pressure washing them clean (not sure how strong the pressure washer was). I read that even soft brushing them can pick up sand and scratch your specimen
