How do you open a zipper that is stuck from salt water?

To open a zipper stuck from salt water, start by rinsing the zipper with fresh water to remove salt deposits. Then, apply a lubricant like silicone spray, WD-40, or even a small amount of soap to the zipper teeth and slider. Gently wiggle the zipper pull back and forth to loosen it, being careful not to force it. If it still doesn’t budge, repeat the lubrication process and try again.
