Due to having stickered parts, I wasn't yet able to peroxide a couple of parts or the breast-beasts, but I've received some reprostickers which look pretty good, so they'll get a much needed bath somewhere this week (depending on the weather).
A good tip I read was to place the items + H2O2 solution in a (strong) zip-lock bag, instead of in a container. It allows for almost maximal exposure to UV-light, AND allows for easy turning of parts to the UV-source. I have to say, I also really like the tip to use a mirror to reflect some extra light back.

Wouldn't put zip loc bag out in sun with a chemical in it, especially on a mirror. Ziploc bag should get hot enough that it would melt and leak.
Glass containers (such as a cookie jar, baking glassware, etc) is most recommended.

I live in Northern Europe, where even on a sunny day, the temperature rarely passes 80 degrees . There's literally no chance of zip-loc bags melting over here, even with a mirror under it. I use 3% peroxide, which shouldn't be nearly strong enough to disolve the plastic either. For my relatively high latitude, I'm thinking it's better to use a container that absorbs the least amount of the UV light as is possible, considering the strength of the sun's rays is less than it is at lower latitudes.
Of course, in countries (nearer the equator) with much stronger / hotter sunlight than we have in Northern Europe, you may very well be right in saying the use of plastic containers is a risk.
