Cleaning up a headbadge

[Ernbar]

What is the best method for cleaning up this headbadge on my 46 Rollfast without damaging the red paint on the letters and circle or just leave it as is?

Looks like it might be a nickel plated brass badge. Try some vinegar and a Q-tip on a spot.

Thanks GT Tried it on a spot but the vinegar takes off the plating so I stopped. I will leave the patina as is.

This is one of the hardest badges to restore. You really need to find a good original one.

I think this one will look ok since I will leave the patina on the bike so it will not look out of place.
