A buddy touched lead then my guitar, bad?

A buddy and I were carrying bags of lead to my dads shed cause they are used to lay on a lead sled (a stand that helps sight in a firearm) so we didn't really touch the lead directly but it could be on the bag a little bit. But we went inside and he was looking at one of my guitars and touched it in two places to lean it from the stand. After he left I wiped it with a very very slightly damp towel. I was wondering if It is clean and no residue of lead is there. Even without wiping it would there be anything on it and if so would it be harmful? How should I clean it of if there is something left on it? Or am I just getting crazy for nothing?

Thanks for your time!!
