Whatever means of lubrication you use, and whatever buffer you choose to use (Mylar, chamois), you need to make absolutely certain that the surface and buffer are clean and free of any sort of metal filings, dist, debris, dirt, etc., as these will all cause unnecessary scratching and hinder the best flow/glide of the magnet across the work surface. We recommend a good quality commercial spray wax because it is usually no fuss, no muss. If you look at the contents, many spray cleaners no longer contain any sort of wax.
