Salt Stains on Suede Boots

I just use an old soft bristled toothbrush to remove as much of the salt residue as possible, wipe with a damp rag, then lightly rough the suede up with the toothbrush again and allow to dry. I've had my snow boots for 19 years (16 winters of which were worn in highly salted Michigan instead of the sand used here in Washington State where I live now) and they still look almost new.
