Taxidermists? - Help my spider!

I'm not really sure where else to ask this question. I recently started mounting tarantulas as a hobby. They come from distributers online, prestuffed and folded. I've been getting the hang of it! But one spider I accidentally over-hydrated then left in the sun. My bad, now he kind of stinks... Anyone have any suggestions how I can correct this? I've been Febreezing him while he dries, but if I can't get him to smell better I might have to throw him out.
