Etching plastic with hydrogen peroxide

From:Gayle Callis <>

Never etched plastic with hydrogen peroxide unless this breaks some of the
polymer bonding?

Have used 1% formic acid to mildly decalcify a few micrometers of bone on a
polished section of bone embedded in methylmethacrylate (7200 has GMA and
PMMA?? or just PMMA) in order to improve dye penetration into the bone.  OR
etch plastic surface with xylene, for a bit of removal and softening of
surface. There are other solvents that will do the same thing.  

Hopefully Richard Horobin will make some comments on hydrogen peroxide???
