Go buy yourself facial cotton wool pads and surgical spirits, pour spirits on the cotton wool pad, gently dab on to the cold sore ensuring the whole sore gets a good dousing. Do not rub or scub just saturate it. The let it dry - do this at least 4 times per day, I do this for pimples when I get them, clears them chop chop
try it
BEWARE- IT WILL STING LIKE SHIT!
