you bet!
These brass burners were pretty badly tarnished. They've come up wonderfully (& with very little elbow grease).
I just gave them a light buff with steel wool after they had soaked in Coke for a few days. If you're going to have a crack at this...
-Get an airtight container (to keep the bubbles bubbling longer).
-Place your burners in the container & fill with Coke until they are well covered.
-Regularly change the Coke over the next couple of days.
-Buff with steel wool (not jex...the real stuff).
