I wouldn't submerge them. I'd clean the jaws with hot, soapy water- then wipe them with alcohol wipes. Can you see the needle? How deep is it? It is important that you recognize what you can and can't do yourself. If I could see it - I'd pull or cut it out myself. Otherwise, it's too deep. Please don't drive it in deeper! If none is sticking out, then you have to cut around it! If you have any doubts - go ahead and go the hospital bro.
