need to clean my hands for wedding...

I'm guessing this is a pretty nice affair and the groom's party is wearing rented tuxes? If so, talk to the tux rental shop and see if they can provide the groom's party with some nice evening gloves. Just in case your's won't come geeky clean. It worked for me more than once and the way I look at it, if they really want me to be there in that capacity they won't mind the extra expense or expect me to wreck my skin. After all, they knew what I did for a living when they asked.
