One should never use plastic bottles to store CS. My experiance has been that the plastic in the areas of bends like at the bottom of the bottle gets very thin and lets in considerable light. You can check this yourself - just look inside a plastic bottle an you will see plenty of light coming in from the molded plastic bottoms, this is particularly bad in the cheap peroxide bottles. Second there is some concern about electrostatically charged plastics that can attract the silver particles and render the CS less effective. So why take a chance - the best solution is to use deep amber bottles with non matalic tops - best would be the amber lab bottles with amber glass stoppers. Chris Gupta
