[QUOTE="AtomRat, post: 102947, member: 3111"] I found a great link here that explains what hydrochloric, hydrofluoric and alibright ( which has 1% hydrofluoric ) if anyone wants to check it out: [url]http://www.gold-prospecting-wa.com/cleaning-gold.html[/url] Working with Hydrofluoric Acid: [url]http://www.commerce.wa.gov.au/publications/working-hydrofluoric-acid[/url] Also found a comment elsewhere by Oneday69: [i]when cleaning species I use a solution of 10% hydrofluric acid with all the neccessary parafinaliar to boot. If you dont take precaution with this acid then DO NOT USE IT. The quartz comes out white and the gold is yellow. Full strength acid will devour the rock to liquid.[/i] [/QUOTE]
