That's why the ZeroTol is stabilized. While I would still avoid metals, it
is MUCH safer to work with than concentrated hydrogen peroxide - and I've
worked with both.

IIRC, concentrated H2O2 can be had cheaper than Zerotol.

Keep in mind that it is nasty stuff. Pour it in a metal bucket, and
you can get a steam explosion. It breaks down violently in the
presence of metal catalysts like iron and copper.
