I am new here. Can anyone guide me in cleaning process for this fluorite?I want to remove the coating on it.Thank you

Hydrochloric acid will do no harm to fluorite and can be used to remove carbonates and iron stainings as well.
Stay way from oxalic acid it - you would get dull faces!
The Waller Solution works well, though, and should be applicated after a HCl treatement.

Do you know where your fluorite is from?

FYI
Super Iron Out (SIO) is now just called > Iron Out (IO)...
So don't look for the "Super", unless they have old stock.
But the company assures us the formula is still the same as SIO, no change there.

The solubility of fluorite in HCl is about 20 times higher than in water. But still, this is yet practically insoluble and will not 'etch' the fluorite or generate HF in a dangerous concentration.
Although, it is very questionable that any treatment will solve the layer. It is well possible that Doug and Susan are right, but you can give a try with HCl and no risk.

(I am a long time away from the theory of solubility!)
