Several of my upper cabinet hinges are sticking. Dunno what they're called but these are the "swing arm with a spring" style hinges. The two outer pivot points are rubbing against the cabinet-side bracket. See circled areas in the pictures below.
There are no gaps and nothing is bent. I've tried silicon lubricant but that doesn't help.
The only solution that comes to mind is to remove the hinge and grind down the part of the bracket where it's sticking. That sounds like something that could easily make matters worse. Has anyone encountered this before? Any quick fixes?
