Sorry, no photo, but maybe I can dispel some gas with a better 
description. Picture a wood block, maybe 1"x 2"x 3/4" thick, with a 
piece of upright hammer rail cloth glued to one side. That cloth is the 
pad that holds the wet pumice, and the wood block is the handle. I keep 
a shallow flat bottomed bowl with a little water in it close by, dip the 
cloth in the water (holding the handle), sprinkle on a pinch of pumice, 
and scrub the pumice into the key top with the cloth. Repeat until gloss 
is gone from the key top. Move on to next key top. It's just like 
sanding, only the pumice supplies the abrasive grit and the hammer rail 
cloth replaces the paper.
