I was tidying up a surfboard for sale and found the zip sliders on the board bag were jammed with corrosion. I was using hot soapy water to wash the wax residue off the board so I soaked the sliders in the water and they freed up nicely.
I did the same thing to an old board bag that had been corroded up for about a year and it is now easy to slide.
The sliders will probably corrode again pretty quickly but it's easy enough to give them a wash from time to time. That's better than buying a new bag or putting on new zips or sliders.
I have read on the internet that vinegar works well. Apparently urine also works.
I don't know of anything that will prevent the corrosion. I have tried silicone lube and that has no effect.

Use it on the boat zippers and just about everwhere else ! It contains lanolin of a sheeps coat Great corrosion resistance to salt . !
Bumblings also sell a silicon spray in a light green can - usually found in the curtain track and blinds aisle.
ideal for curtain tracks, and the zippers on those clear plastic café curtain thingos.
[which is why it is found in the curtain aisle]
