Crack it and get it into acetone if you're not majorly out-of-pocket on it. If you do, seal it into the acetone bath, leave it in a chill area away from the sun so the acetone doesn't evaporate or heat up, and don't revisit it for 48 hours. Then swish the snot out of it in about a pint of fresh acetone (held with tongs), and seal it into another soak. Lather, rinse, repeat until it goes away. If it ever does. Proofs cannot be touched with anything physical (except to hold them by the rims) during conservation. I only touch Proofs with rose thorns under magnification and even then only when the touch never comtacts the coin (when the buildup has z-axis projection from the surface). And then only when I can leverage gravity to make what I touch fall away instead of moving on the surface. While submerged. Conservation can be....complex if you want to do it right. It's material-intensive - I've thrown whole quarts of acetone at a single coin - and exacting (you better have the hands of a machinist).
