Using sand paper will provide a temporary shiny surface, no doubt. What it will also do is provide microscopic and not-so-microscopic scratches in the brass where dirt and other stuff can take up housekeeping, interrupting electrical continuity.
But, each to his own. I think the LGB cleaning block is the best, followed closely by a drywall sander.
OTOH, switch to battery, and you won’t have to worry about it.
The devil made me say it! I swear, I had no control over my fingers!

Hey Steve,
I am aware that there is different sand-paper available, i use 280 grit or higher, and i prefer any thing which is not just coated paper, i prefer cloth sheets.
Regarding the microscopic scratches: I guess it is a matter how big a magnification that microscope has, but scratches always remain when you sand, that even with the finest grit.
The LGB cleaning block is flat, and if you look at the detail 5x magnified, it should explain that theoretically it does not necessary clean where the wheel touches. Just guessing, but a cleaning block with two times 3 degree angle could eventually do a better job.
