[QUOTE="bjbear46, post: 495814, member: 15153"] I've been using Digger's Rust and Stain Remover on some Amethyst & Quartz I found recently at Kuridala. It's 100% Oxalic Acid in powder form. After a couple of weeks soaking and brushing every so often, I gave them a blast with a pressure cleaner and most of the dirt and staining was gone. Most Lapidary clubs are only too willing to cut up rocks. You might have to pay a nominal fee but it wouldn't be much, I wouldn't think, and it would be done properly and safetly. [/QUOTE]
