Quick way to get rid of chlorine in the bath water (to make the water purer, great for anyone with sensitivities to chlorine or chemicals): Go to the pet store and buy chlorine-neutralizing drops sold for fish tanks. I'm very sensitive to chemicals, and this type of drop has a simple reaction with chlorine and hard metals in the water, forming them into a form that is inert. The drops aren't even noticable to me (and i'm sensitive to everything), and the water is noticabally nicer without the chlorine. It only takes about 25 drops to do a bath tub full, and my bottle lasts me months.
