I believe the formula of WD-40 is solvent and water emulsion. So, what one dissolves the other gets under it preventing it remain a film. The citrus oils in cleaners naturally combine an oil and water type liquid. Ask some Navy carrier vet; conserving water at sea, aircraft are cleaned with hand cleaner. Even exhaust soot. You won't believe how gritty/ cream hand cleaners wail on grease or rust. The abrasive is too soft {Mohs scale] for any damage on machined surface.
