This URL sort of suggests watering a lot and gypsum to dilute the salt.

"The best thing to do if you are facing this situation is to pass large
quantities of water through the soil, trying to leach the mineral salts
out of the root zone. This can be enhanced by the application of
powdered gypsum.
Gypsum binds with salt ions and helps to carry them through the soil.
Apply at least 10 pounds per 100 square feet, and water, water, water.
If the water starts to run off, stop and let it soak in for a while.
Then repeat for as long of an interval as possible without run-off.
Cycle through many times and hope for the best. To avoid some of this
danger, and fertilize more effectively, read this article"

As I recall, the Dutch use gypsum to repair fields that are damaged with
salt when a sea dike fails.
