Somebody help, please! I don’t know what to do? 
I mean, I wouldn't eat off them like that. I suggest washing them with regular dishwashing equipment first.  Your dishes aren't ruined or anything. A big reason they're made out of something non-porous, like ceramic or metal or plastic, is so you can scrub them clean with soap and water without any food or, uh, other stuff getting stuck inside them. The scrubbing clears off any macroscopic dirt, and the soap both rinses off microscopic stuff and kills a lot of microorganisms. If cleaning dishes with normal methods weren't enough to get rid of dangerous germs, a whole lot more people would get food poisoning.
