I found these solutions:
Pour a solution of one part white distilled vinegar and one part cold water into a spray bottle. Spray a generous amount of the diluted vinegar onto the stained chrome and let it sit for five to 10 minutes. This allows the magnesium chloride to be absorbed and dissolve in the solution. Blot the chrome dry using a lint-free cloth.
Mix 1/2 cup each of flour, salt and white vinegar to form a paste. Use this to clean more stubborn magnesium chloride stains. Gently rub the paste onto the chrome surface, and then leave it on for at least one hour. Use a soft bristled brush, such as a toothbrush, to clean up the paste, and wipe the surface clean with a dry cloth.
Use a poultice of oxalic acid to get rid of the magnesium chloride. Dampen a gauze pad with some oxalic acid and blot it onto the stained chrome surface. The acid gets rid of the stain by neutralizing the pH of the magnesium chloride, which is highly alkaline. Rinse off the acid with cold water, and dry it using a soft, lint-free cloth
