forgot to mention, i started cleaning with a solution of one part vinegar to three parts water. success! i don't mind the smell. ... reminds me of the salt n vinegar potato chips i love so much. and i can inhale it without worrying about what's going into my lungs!
also: if you have cats, try mixing "feline pine" brand natural cat litter with arm n hammer baking soda to deodorize. it clumps very dry, and so far no ammonia smell! my cats are happier "people," i swear!
i forgot to mention about the kids: they've been playing an amazing game of make believe together all DAY! i am so impressed. ; )
