Advice for removing bluish/green saltwater corrosion from zippers

[RioReefr]

Okay, so a bit off topic but suspect someone here might have some good advice for removing saltwater corrosion off metal zippers?

I took my backpack and camera bag to do some snorkeling for a few days. They got wet and now all the zippers have bluish/green corrosion on them. I tried WD-40 (a lot actually), but it made no difference.

I read soaking the bags in water solution of baking solution might work, but looking for any ideas at all.

I spray the zippers in my boat and tent with Silicone spray. WD40 is quite corrosive on many plastics, rubber and cloth. I don’t think it’s the best way to remove the corrosion but it is certainly the best way to prevent it.

To remove what you have you could try CLR but again I would be concerned about the corrosive effect on the cloth, so do some research first. It is great on hard surfaces, but not sure what else it is safe on.

Throw them in the washing machine and along with your regular detergent add a can of coca cola. Yes put in a can of Coke. If you can't machine wash them soak them in a bucket with Coke and laundry detergent for a couple hours and rinse. Then silicon spray as Tastee recommended. Or rub with chap stick.

Coke in the wash is also great at removing that nasty fish stank from your fishing clothes.
