I'd guess there is some soap scum down in the works. I'd give it a good bath in some scrubbing bubbles. If that's not available soak it in some water that has boiled (but don't boil the water with the razor actually in the pan). Repeat until you don't see junk in the water.
Edit: To your question about damage - it is possible to damage it, as the spring that gives the adjuster the "click" is put under more pressure while the doors are down.
