I know some people keep their Plantex CSM +B solutions in the fridge. I always used to add mine dry (big tank makes this easier).
As for cleaning, I'd give it a quick scrub with really hot water to get the easy stuff out and then submerge it over night in a bleach solution. Give it a reall thorough rinse in hot water again and then give it a soak submerged in water with more than the normal amount of dechlorinator added (2-3x the normal amount is usually what ive done).
