 First, although kimwipes leave little lint, they do
leave some.
 As a person that has done mirror grinding, I can tell
you that one of the most sensitive ways to see if there
is anything stuck to the surface is with your finger.
You can feel things that you can't even see. It
is quite likely that there was still something on the
heads surface. If you use your finger to check the surface,
you can follow with one of those foam swabs and alcohol.
You should first clean as much oil from your finger before
using it to test the surface with some alcohol as well.
 Also watch out for the back edge of the heads. These
are often very sharp and if you rotate the disk backwards
against the head, it will dig into the disk surface.
 Anyway, feel the surface of the heads with your finger
before you consider that you have removed all the gunk
that could do damage. It should be silky smooth.
