Re: [Phys-l] removing labels



Also: If the label is reeeally baked on and you reeeally want
to remove it, you can consider using piranha etch:

This will destroy any organic material.

Warning: fingers are organic.

This is seriously powerful stuff, but relative to so-called
"chromic acid" etching it is no worse, and is incomparably
greener and easier to dispose of afterwards.

You can obtain 30% hydrogen peroxide at beauty supply stores.
This is not to be confused with the 3% stuff you get at the
supermarket!
