Yeah, even in an
emergency situation you want to let the salt fully mix for 2-3 hrs before using it. Of course every salt is a little different, some brands dissolve faster than others. I probably go a bit overboard, but I like to let mine mix overnight (12 hrs minimum) before using it.
The only thing I can think you could do is try giving him a 1 hr bath using either Methylene Blue or Malachite Green (see below). Both help heal ammonia burn, so it might work on "salt burn" as well. I believe Petco/smart and even some Walmarts carry this product:

Malachite Green/Methylene Blue: Treats ammonia burn, cuts, injuries.
How To Treat - Comes in both liquid and powder form, sometimes mixed in with another medication(s). So, follow the directions on the label. Best used as a 30 minute bath solution, but you also can treat with it in a quarantine tank. Aerate heavily. If you are using it in a bath solution, then it is also a good idea to treat the fish with nitrofurazone (active ingredient found in
Furan-2 and
Nitrofuracin Green Powder) once he is returned to the quarantine tank. Nitrofurazone is great for treating open wounds or sores.
Pros - Highly effective.
Cons/Side Effects - Depletes oxygen from the water. Malachite Green is considered “harsher” on fish than Methylene Blue.
