The magic skunk-smell-be-gone recipe:
In a plastic bucket, mix well the following ingredients:
First thing you want to do is get as much of the skunk goo off of you as you can. Using paper towel, tissues, or a rag you can throw away, dab the spray off your skin. Rinsing with water does not work because the skunk spray is oil based.
Go somewhere with a shower, get as much of the stuff off of you as you can with a rag/towel, shower (soap very well), then wash any areas that still smell using the H2O2 concoction. Note: H2O2 breaks down quick so use the stuff immediately after mixing.
Breath through your mouth. Burn your clothes. But seriously... remove your affected clothes and put them in a plastic bag (to burn later-or wash). Remember that the spray is an oil, so washing in creek water will just spread it around and not necessarily wash it off, dab off as much as you can, wash up to the best of your abilities and then just deal with the smell. There really isn't much else you can do. If the smell is making you gag, put some sap on your lip, or pee into a rag and tie it around your face (it works for mustard gas...).
