What's wrong with a good old fashioned Chamois Leather and a bit of elbow grease.
The Morgan doesn't have that big a surface area after all and I bet it wouldn't take that much longer.
It’s not the surface area Bob, it’s a case of getting all of the water out of the nooks and crannies that are prone to corrosion, of which there are many on a Morgan, wing beading, runner board strips, badges etc..
