subject: ATM Can CeO2 `etch` a polished mirror?

I warm pressed a new lap on my mirror a few weeks ago, using CeO2 slurry. 
I removed the tool /lap, but neglected to clean up the mirror.
 The water slowly dried out.  When I started back in on things tonight,
I saw some blemishes on the polished surface.  No solvent would remove
them.  They are not scratches, but look like a residue, except that they
won't clean off.  I can't feel them with finger or fingernail.  I'm about
to see if polishing will remove them, but has anybody experienced this
before?
