What exactly do you mean sterilize needles? Most needles come in a single use package or with a "protective cover" on it, which means it is sterile until you remove that cover. You wouldnt take an alcohol swab and wipe a needle off because of the chance of sticking yourself. No medical proffesional is going to use a needle that isnt sterile(hence in a protective cover or package). The only risk of contamination by the needle is AFTER it is used on the patient which is why there are "safety devices" on them. After used you activate the safety which means you are putting a cover on it that is already attached to it. You simple push it up(on most) and put it directly into a sharps container...
