[QUOTE="Guest, post: 16473"] Try allibrite (Supercheap). Have been told it will clean quartz off but needs to be changed every couple of days & could take a week or longer. I have used it to clean up a specimen but wanted to keep the quartz attached so it only went in for a few hours. Came up good. For ironstone etc. I have been told brickies acid from Bunnings does the trick but again can take up to a week or longer. If lucky enough to get a large specimen you may be able to find a "trustworthy" industrial cleaning place with an acid bath? (Or use the thermal shock method above - tried to find some info I had read on this but can't remember where I seen it). Keep in mind that most specimen gold is worth more than the gold weight also.
