Many thanks for the replies guys. Much appreciated.

Should finish the machining of this batch by the end of the week, then begins the abrading to soften the edges, then the polishing and cleaning. Some small spaces to get into..!

Wal,

Whatever you end up using I feel that you will not go far wrong using an ultrasonic cleaning bath; this ensure that EVERY nook and cranny is cleaned.

Cheers, Martin

Neutracon is the neutral version from decon that is fine for brass.

Just thought I'd post back with a bit more on how this has gone / is going.

Post polishing, the plaques look like this:

This is a rough vid describing the clean up stages (soap/rinse/alcohol/rinse):

From there the plaques go straight into new plastic bags and won't be touched again until they're up for paint.

Water lies evenly across the floor of the recessed areas after the alcohol has been rinsed off, so should be good.
