Most of the light tarnish on the smaller items is removed on a bench grinder fitted with a bundle of fine scotchbrite discs. However I have tried by hand to do the larger parts and it is soul destroying. I use a fine pad that does not affect the metal. I have tried a few experiments but the one below seems to take the some of the effort out of it.

The above it is an air mini orbital sander.  To the velcro pad I attach a 50mm disc of scotchbrite and use this with oil to gradually clean up the metal. The pad seems to stick well to the velco – more by luck than judgement! As you will see below, ask the metal is starting to clean up well and when finished should look good.

This process will also be applied to the tilting table.

After a good going over with the ‘air brush’ I will give it a final hand polish with an ultra fine scotchbrite pad. The results so far are not bad!
