The oxidation removal from brass items is essential to their upkeep. Brass is a zinc-copper alloy, and is prone to oxidation. When brass is manufactured it is covered in a lacquer which makes it airtight. As this is worn away through time and use, oxidation sets in.
Step 1 - Clean the Brass
Wash the brass to be cleaned in warm soapy water. Once thoroughly cleaned, dry the items using the drying cloth.
Step 2 - Remove Old Lacquer
Put on the rubber gloves. Using the acetone and cotton wool balls, gently rub the brass until the old lacquer is removed. For awkward places, use the toothbrush. Obviously, throw the toothbrush away or put it in a toolbox.
Step 3 - Remove Tarnish and Oxidation
Using the soft cloth, and a little bit of brass cleaner, gently rub the brass in the direction of the grain rather than circular motions. Try to generate heat as you polish, as this helps to break up the atoms which cause oxidation. For heavily tarnished items, use fine steel wool. Once the brass item is completely polished, in which case it will be covered in a fine chalky film, take the second cloth and polish the brass until the desired finish is achieved.
Step 4 - Apply Lacquer
Spray the lacquer on in thin coats to avoid drips. Follow manufactures instructions. Always spray in a well ventilated room. Tidy away equipment and dispose of gloves.
