what can i add to wings that were frozen in a soy sauce to save them
If there's sauce stuck to them, you could just wash them thoroughly. If they're seriously overmarinated, salty all the way through, you could try soaking in water to try to pull some of it back out.

If none of that works, Joe's suggestion of adding bitter flavors could work, up to a point, but it won't be the recipe you had in mind originally.

You could also add or serve with something bulky that isn't salty at all. This is a bit tricky with wings; it might have to be a sauce, since you can't exactly just toss in potatoes or vegetables and expect to eat it all together easily.
