What is the effect of heat on bleach? I currently keep my bleach in the laundry room till time to use, but I have been thinking of keeping it in the storage shed out by the pool. I know over a long period of time it will diminish the strength of the bleach, but what about just a couple weeks?Anyone know for sure? Or anyone have a wild guess or educated guess?

Check out the table near the bottom of this page for a table that can help answer your question. You can see that a lower concentration of chlorine lasts a LOT longer even at higher temperatures. Note, however, that impurities in the product can have the chlorine degrade rather quickly no matter what you do so a quality product is important.
