Removing Cat Spray from Human Hair?
Ive never tried this, but I do rely on white vinegar to get all sorts of smells out of things - cat pee from a jacket, skunk from a dog so you might have some luck.. couldnt hurt!
Cleaning a Posturepedic Mattress?
I totally believe in white vinegar. I would think on a sunny or dry day you should try to spray it on the exposed mattress (wash the cover with white vinegar in place of bleach and in place of softner). Cheap try!
