Yes, but this one wouldn't get off the grease, only spread it.
You still need IPA later.

There is a whole range of products well suited, like the abrasive pads
for copper plumbing (to prepare for soldering).

The 600 grit paper gives a certain roughness, which can't be bad for 
adhesion.
But i think it would work with a much smoother surface too.
