I can highly recommend WT-40 Contact Cleaner (NOT 'normal' WT-40) which is a non-polar solvent designed for cleaning of electrical circuits and contacts. Or many other contact cleaners (I live in the UK). Leaves no residues at all. In my experience, anything that contains water (i.e. any alcohols) is unusable as water promotes oxydation (the black gunk we all hate) rather than prevents it. Any 99% alcohol after some time will contain a lot of water as the alcohol itself is so hygroscopic taking moisture out of the air when open. Other opinions are available.
I'm not arguing, but. Wiping any rail with any abrasive can lead to other problems. I quit using bright boy, sand paper and certainly never a file. My current favorite is a white wine bottle cork. And even that is rare. But to clean points, etc. I only use a liquid. As I mentioned, acetone would work, but can harm ties. So the best thing is to start with alcohol, and then the mineral spirits. That I have done and does work.? ?Morgan Bilbo, slightly over one year with very basic DCC
