Removing oxalic acid residue from crystals

(1/1)

rgeagr4ea:
Hello I'm not sure where to post this sorry if this is in the wrong section. I have quartz crystals that I use oxalic acid to clean; I got impatient and used too much oxalic acid powder in solution and it has left a hard white chalky residue on my crystals that I can not get out. I think it's calcium carbonate residue. I hope my crystals are not ruined.

I need the help of chemists; what can I do to remove this residue? It doesn't come off in water or with scrubbing. I also tried using concentrated acetic acid but that doesn't help either. Thanks for your help.

you have probably left oxalic acid on it. It should dissolve in alcohol try wiping with that.

rgeagr4ea:
I just tried, still didn't dissolve any :/
