CD Bath question...

I was wondering, can I prepare the CD into thermos made of stainless steel? On hot days is good to keep it cool if you need to go places....can I put CD into metal bath, I live in Mexico and standard bathtub will not fit, so I have to use hand made metal bath would that be ok for CD? Thank you

I don't think that would be a good idea. Many times stainless steel thermoses are glass inside. If yours is this will work fine.

Bath- If the tub is small enough can it be lined with something? Say, for example, a couple shower curtains taped and sealed up together? or even if you must some plastic trash bags taped and sealed together?

Chlorine dioxide as a sanitiser in contact with stainless steels.

Chlorine dioxide (ClO2), occurs naturally as a gas, but is normally dissolved in water, as the gas is highly explosive.
Although a powerful oxidiser, unlike chlorine it does not breakdown to release chlorides. The chlorine and oxygen work together tending to form chlorites in the oxidation process. Although the chlorite can break down to form chlorides, it is a weaker oxidising agent than the chlorine dioxide and so can be expected to be less of a hazard to stainless steels when used as a water sanitiser.
