Do not use WD-40, since it can easily travel to the circuit board contacts or other places where it can cause trouble. I would ignore it, or if it gets really bad, take it to an Apple store and see if they want to try and fix it. If that screen goes its $1000, so do not do anything which might void your warranty.
