See if you can find someone local with an ultrasonic cleaning bath.

Geez! Get the schmutz off, but there's no point in being obsessive

But they _do_ need to be dry!

It's pretty cheap these days.
He might even find a local guy to do it for free.
The advantage is that anything in a pore is removed.


Ah, pores! Okay, I've learned something today. I guess I can go back

Wait a minute - how do you know that the new coating will go into those
newly cleaned pores? Or does it just naturally go in by capillary action
or surface tension or adhesion or something?

Thanks!
