Dugway Geodes

[johnd]

Hi

I have a few Dugway geodes  which have a brown stain on the white crystals- - it doesn't power wash off
reminds me of clay

any suggestions for cleaning?  seems like some of the geodes had developed micro- cracks, desert dust got in and is now chemically bound


I haven't tried chemicals of any sort

Try Iron Out, usually available at Walmart or most hardware stores. If you use warm to almost hot water(not boiling) it helps the cleaning

I found iron out crystals at I think Walmart. I put it in a bucket with my crystals that I had scrubbed with a couple different soaps and remained brownish in color. I forgot about them and they soaked all day. They are so crystal clear now and sparkle. Couple even have mika inclusions (at least that's what I think it is, thin silvery flash) that I didn't see before. Thank you dshanpnw 😊

Thanks for suggestions
I had CLR cleaner and a rust removal gel at home- tested them and have made some headway- I'll keep working at it
