Many thanks for the quick response. It sounds as though you are describing ways to store already mixed and perhaps already used solutions. Good to know! I've also heard it suggested that displacing the air above the solutions with something without oxygen, propane, butane, canned "air" is efficacious. I would guess that the choice of plastic bottles might be significant, since I've read that some plastics allow diffusion of gases through the plastic.
