Tim JF Cuss UK asks about the use of oxylic acid in the treatment
of veroa.
 
From my photographic background, I can share that oxylic acid dissolves the
bones of the living human operator, over time of course, and when used
without a proper fume hood or other protection.
 
This is another solution that sounds like nasty desperation.
Other's mileage may vary - just my nickel's worth of knowledge.
