...my Norton's got mold.
I wanted to work on my Special No 1 today and when I pulled out the hone it had blueish spots all over the white side.

I immediately sprayed it with bleach and then proceeded to lap it with my 1000.
It's good that I did, too, because it wasn't perfectly flat any more. Anyhow, after lapping for at least 10 minutes, the blue spots/stains have faded but are still there.

Should I continue, maybe even use the 220, until they're gone? Or is it ok for now?

Anyhow, I'm letting it soak in bleach for now.

I feel like such a filthy animal....
