Can anyone help me with getting salt staings out? One of my businesses has a over zealous groundskeeper that DUMPS the salt down during the winter and it gets tracted into the building really bad. Their is the real salt and the artificial stuff, you know the little white pellets. It leaves these really nasty white stains everywhere and my vacuum cleaner just doesn't do the job. Is there anykind of solution that will take out the salt stains? Please help! Thanks!
