^^^^ I am ignoring this user^^^^----------One thing to remember about using WD-40, Harry. It is a mild solvent and degreaser and was made for breaking down grease and grime as you say. But since it is a light oil, you are supposed to clean the oil off because it will leave a film. I would then oil it with a good oil- something like Clenzoil. That is what I did recently with my Remington 552 BDL deluxe that I hadn't cleaned in years. Now it works as slick as a whistle. Good luck and thanks for posting.
WD-40 is a water displacing lubricant and rust preventive, not a solvent or especially, not a degreaser. Mineral spirits, acetone, lacquer thinner etc are solvents. I've never had any problems with WD-40, but I've only been using it for 60 years.
