For what it's worth, I used to have fits trying to get the metal filings out of my 320 grit norton bench stone. I tried everything. I had to grow satisfied with so-so results until one day I tried lacquer thinnner, the stuff they use for thinning automotive spray paint. Wow!!! What a difference. It seems to magically lift everything right out of the stone.
