Illinois hunter

This may have been asked a million times but I need a fix desperately! My shorthair took a point blank spray from skunk. Ive tried Fabreeze, Vinager+water, Bakingsoda+soap detergent+peroxide, douche, shampoo. It wont go away. She is usually an inside dog, but not till this is remedied. I have a big test coming up with her next weekend and would like to resolve the smell before she is around all the people. What are some of the most popular sure-fire tricks of the trade for this?
