Hi.
WD40 will leave a fine film of lubricant after the solvent evaporates. Used virtually every contact cleaner available to mankind (55 years between a TV engineer and hobbyist) I always go back to WD40. Duck oil is good too as is believe it or not clear Waxoil but in very small quantities. Switch cleaner is a short term answer as it dries out and then with the lack of lube the track wears faster.
