I'll try the scotch brite and steel wool and emery board methods
first. What is the 3M product that you were thinking of, Norah?
I've totally forgotten the name for sure but I'm thinking it is
exactly the same as Scotch Brite
According to one of my catalogs, they're called: "3M Scotchbrite Hand
Pads" and they're found everywhere.... Rio, Swest, any other tool
supply place as well as hardware stores and the grocery store! When
I"m in a pickle, I'll use a clean one from the kitchen! I also use
these on wax... used lightly they take out imperfections, love 'em.
They come in different colors, used the grey one for years (it was
recommended), and was very happy. But then, was in a pinch and
needed a clean one for wax and grabbed one from under the kitchen
sink, happened to be green and loved it.
I would suggest using the grey and the maroon on metal. The grey is
the finest, the maroon is one step heavier. The green is a dream on
wax, haven't ventured on metal yet, it would probably work just
