>how do I store it?Separate it from all your other gear. Put it in some plastic bags with some desiccant until you can get it professionally cleaned. If you have access to a UV light, put it under it for a few days, this can kill many types of fungus and stop it from getting worse.
>Can I use it with my camera or will it spread?It can spread. Don't put it on any camera, at least any camera that you care about. It's not instant screaming death to anything it comes near, but it's better not to take the risk.
