For the tube mech lovers out there especially brass and copper.
I’m an old fan of Brasso from being in the military. Had a couple of tubes that just weren’t really getting a shine on with it. Saw some chatter about Blue Magic and tried it. Much more aggressive than Brasso and got the shine out of the worst of the batch.
I know brasso… I use it too on mine…
will have to look into that… but I like the patina look on mine… I just clean the contacts and where it all screws together…
They last for ages - if you store them in a plastic bag. I just keep using them until they are completely black. Check ebay for combo packs of yellow and blue for about $2 per cloth
