In my research before refurbishing a vintage Singer, I learned about "ProtectAll". The product is a spray application that cleans, polishes, waxes and has UV blockers. After removing the top layer of grime with water and Dawn, I use the ProtectAll on all my sewing machines. The machines become shiny and the surface is so smooth. The product is normally used for cars, RVs, boats and motorcycles. I've used it on my Corian counters and a laminate sewing table.
Walmart carries it in the automotive section
