[Rockhounds] Super Iron Out

[Earl R. Verbeek]

I've had one negative experience with Iron Out too, with a specimen of
Arkansas wavellite.  It took most of the iron stain off the specimen but
left the wavellite lusterless.  I'm still not sure if the solution
attacked the wavellite or deposited a coating on its surface.  The same
specimen had been treated with oxalic acid before, but part of the iron
stain proved stubborn to remove, so I tried Iron Out.  Suggestions
welcome if anyone if familiar with this particular problem...

            Thanks-   Earl Verbeek

I have only had one bad experience with Iron-Out. Although I have used
it on 
Pyrite with good results, it created a black (lead sulphate?) coating on

weathered Galena. That was subsequently removed with detergent.
