If you can find it, try "Super Iron Out" (not the regular "Iron Out"). It seems to be the cleaner of choice for quartz where it is available - works well, not as dangerous as commercially available acids. (Still, be careful - it IS a harsh chemical compound...)
Otherwise you can try oxalic acid, available at most hardware stores in the masonary supply section. Usually comes in boxes of powder that you mix with water. (Use all necessary precautions for working with an acid.)
Best of luck.

If the specimen is dulled by anything more than iron stains it is probably as good as it's going to get without polishing it mechanically, which will reduce the value of the specimen to practically nothing.

Some of the Guerrero amethyst specimens were coated with bees wax by the locals to make them look better. It may be that you specimens just has an accumulation of dirt caught by the bees wax. I would first just give it a bath in good hot soapy water and see if that does some good. Failing that try the iron out stuff.

That is "Super Iron Out", Rock. The "Iron Out" is a different formula, and is not as good. We have this from chemists
