I use car wax, and give it a quick buff with a clean soft cloth. It works great and lasts a long, long time. I am always leery of spraying anything near my machine. Even the smallest amount ending up in your bobbin area or tension assembly will give you fits forever. I can control where car wax goes, so I use it. I also sew on a formica topped table, and car wax makes that as slick as ice.
