How do I free up a Zipper 'frozen' or salt embedded?

Problem is you have aluminum corrosion inside the zipper slide. A good soaking in a warm water and vinegar solution will do the trick. As soon as you can get it to move just a little, work it back and forth, flushing it out as you go. The vinegar will not hurt the reg, that is what a lot of us clean them in, just be sure to rinse it and the bag well once you get it free. I lube the zippers with silicone grease. Yea I know it will hold grit but IMO that is better than the zippper slide seizing up again.

Praise the Lord~! After the warm water, vinegar & tooth brush, our son-in-law was here the next day & he worked with the track (not the zipper) and FREED it up. Now I've washed the bag & it is thoroughly drying. I'll put lubricant on the tracks before closing it. Thank you one & all.

Warm water. If that doesn't do it, try vinegar. WD40 will gum it up worse.

Yup... I 2nd walters method, And if that doesen't do it , warm water with Baking soda works well!

I was in the US recently staying with a diver friend, and he brushed a proprietary liquid on a seized zipper. Next day it was free. But he's gone travelling and I can't ask him what it was. Not everything with a zipper is suitable for soaking, and this liquid worked wonderfully.

Does anyone have any idea what it might have been?
