Well, it makes PE bottles brittle from the inside. I store it in glass
now. Should be very clean though.
There are special caps with safety pressure relief, although i was told by
the shop they are not required for H2O2.
I'm thinking to get some medical luer-lock plastic valves and install one
to a bottle cap, for easier dispensing.
