We seem to be in this boat too. Spilled some salt in the pantry cabinet and a few months later we are seeing and feeling the full blown effects on the lower slide. I had to remove both the bottom and top slide to get to this. The brand is Schock Metal, and they don't seem to sell their products through retail. Did anyone else have luck replacing these slides with a soft close, full-open kind? I would like to replace it with one that can be disconnected with a lever so it's easier to clean in the future. And if if not, did you find the replacement slide locally? What brand, were they? This one is 22 inches in length.
