My husband was helping me change my substrate. He uses his shop vac to get all the subtrate out and then we scrub it down. Anyway he was vacuming the marine sand out and the piece on the back of his vac was open and the sand got on my carpet. We got all the sand up, but the green is stained on my beige carpet. How can I get it up? I tried shampooing it and I'm calling in the morning to have someone come out and clean it, but does anyone know a way to get this color out of my carpet?
