Only the reply posted here about the Scotchbrite pads...

Yup.

Did you mean the kitchen-grade Scotchbrite pads sold at the grocery
store, or one of their industrial products?

Industrial product...

Then type "abrasive nylon" in the search box

Then click on "Nylon Mesh Abrasive Pads"

Then look for the different grades. There is a "white" grade out there
somewhere that polishes my polyethylene plastic guards to almost a mirror
finish... You may want to try the finest or next to finest gray silicone
carbide variety... But try it in a hidden place first! No guarantees...
