Chlorox makes a spray, I think it's called "anywhere", this is what we use. Says that it's safe for pacifiers, anything. Don't know how much you can trust that, but it's gotta be safer than a lot of other things like mold and stuff that would grow on toys eventually. I have heard lately though not to overdo it with this kind of thing. It's good for kids to be exposed to germs to so they can build up immunities. I pretty much only use it when one of the kids is sick and to clean tables and stuff where they eat. Hope this helps!
