Why is the tarnish not coming off brass or copper?

If MAAS Metal Polish does not instantly remove tarnish this indicates the metal is lacquered. The lacquer must be removed before cleaning and polishing.

It is best to show the metal item to your local hardware store manager and ask his opinion for the best product and method to remove old lacquer.

Once lacquer is removed MAAS Metal Polish will quickly remove tarnish & oxidation.

To protect against harsh weather and the elements apply MAAS Metal Protector. The protector can be used on all non-porous surfaces and is recommended for indoor and outdoor use. The deep luster is unsurpassed.
