One, your post isn't computer related and second I am a expert in fish, WD40 will pollute rivers and streams and kill fish, Don't do it any more, please.
The best use that I have for WD40 is to spray it on my fishing lures while fishing for Salmon. No kidding, this is the best attraction for fish. Try it!
