I mostly use a nylon brush for routine cleaning, but I have the SS brush for the occasional heavier need. The surface is at least 7 years old and a little rough in spots. The previous owner said refinishing after 10 - 12 years would not be unexpected. Don't know if that's right or not. If so, I'd expect to refinish in 3 - 5 years. I'd probably want to do it anyway to fix the "pockets" that in in floor pop-ups are in.
