Everyone uses the products that work best for them, and/or what's available to them. My preferences may not be someone else's. A bottle of sewing machine oil(brand doesn't matter as long as it's for sewing machines. I use Tri Flow, Singer and Allstitch house brand). a small tube of sewing machine lube, and what ever you like best for cleaning the outside of the machine, as long as it isn't water based or harsh. I use TR3 Resin Glaze on my black machines.
