Re: Re: Re: howto clean quartz

Mr. Betts' article took my thunder. I was about to post an answer, then looked at the reference and saw my answer Oxalic Acid. I would like to emphasize Mr. Betts' part about soaking for 3 days. Remember you are trying to take off what may have taken quite a long time to be placed on the mineral. I have used oxalic acid many years ago (40+) to clean quartz crystals, but now leave them "au natural."
