You laugh, but I had a guy do exactly that when his RT hit the service limit.

Fucking BMW people...

Yep. 440 grit over a piece of glass works wonders, unless the washer has really big ridges on it, in which case I toss it.

For sealing washers (the "folded" crush washers on some drain plugs) no, they are a one time only deal.
