Every manufacturer that printed instructions stated to put nothing on the slides. Once they are clean, you can fine wire brush or 0000 steel wool them to put a slight polish if wanted. Spraying Teflon puts a wet film between slides which can cause a suction. Graphite was available then but I've never seen it recommended. Cleaned, slightly polished slides work perfect. If you have pay issues after cleaning and polishing, then the problem is elsewhere.
