I bought a hydrogen peroxide wipe thing..I think they are clorox..from Amazon. It was like $32.00 for two huge canisters. They are hospital grade and kill noro. I haven't used them yet. I probably should.

they kill noro, rota, etc. You are in the US so if you spend $35, shipping is free! I got a cheap dvd and my son was super happy.
