Keyboard Squeak! Solution workable?

Since I received my ThinkPad, there is an irresistible annoyance sound that comes from the lower right hand corner whenever i place my wrist onto the keyboard. I tighten the screw, no luck... So i tried something different, I opened up the keyboard, and placed some paper, onto the magnesium parts. I did not cover any of the vents, nor do I believe the placed it onto any other wiring parts of the laptop. My only concern about this technique, is whether or not the paper has a chance to catch on fire, and if it will damage any of the finger print+track/touch pad utilities.
