Removing Skunk Smell on Dog?

I am looking for a solution for a lingering skunk smell on my German Shepherd dog. She has had 3 baths with the baking soda/peroxide/dish soap mixture that worked well. But she still stinks, especially after getting wet. I know it takes a long time to completely get rid of the smell. But I am wondering if someone knows of a deodorizer of some sort that I can perhaps spray on her or wipe her down with? Thanks.
