I have a pool deck storage room that covers my filter pump and motor from the elements. I store all the pool toys, cleaning nets, poles and test kit in this room. I also have an area that is separate and also covered on the backside of the storage room. This is where I keep my chemicals, ie. bleach, baking soda, borax, muriatic acid, and stabilizer. The sun never shines in these rooms, but they will get up to 90 plus degrees as the temps warm up. I am curious if this will ruin or degrade the chemicals or test kit agents over time. I don't want to store the acid in the house and I will put the bleach in the laundry room if needed. Any suggestions or will leaving this stuff outside covered be ok?
