How to Clean Copper

Although copper is harder than silver, it is still softer than either brass or bronze. For cleaning purposes, it comes in two varieties – lacquered and unlacquered. Lacquered copper – usually decorative items – has a finish baked on at the factory. Unlacquered copper – mostly cookware – tarnishes easily but will brighten with elbow grease and the right techniques.To clean a copper item with lacquered finish, you only need to dust it as part of your regular cleaning process. If it is dirty, you might want to wipe it with a damp cloth. If cracks appear in the lacquered finish of a piece, it must be stripped of its coating with acetone or paint thinner, applied full strength with a cloth. Or boil the item in a large saucepan or preserving pan, using 4 litres water and 100ml soda crystals, as suggested by cleaners Balham. The lacquer should peel off. Wash with dishwashing  detergent, rinse with running water and dry with a soft cloth. If you want the piece lacquered again, get it done by a professional.Never use any scratchy cleaning tool on copper cookware. You run the risk of leaving marks. And bleach will seriously discolour copper if it stands for a few hours more.Sprinkle the piece with salt and a little white vinegar and rub gently. Alternatively, cut a lemon in half, dip it in salt and rub. And if the piece can stand the heat, boil it in a large pan filled with water, 100ml white vinegar and 50g salt.Whatever method you use, always rinse with fresh water, dry well with a tea towel and buff with a soft cloth. If you want more shine, apply a commercial copper cleaner according to label directions.Crevices can be tough to clean and can be magnets for paste-polish build-up. Use a cotton bud or natural horsehair brush and methylated spirits to banish the grime, as advised by cleaners Balham.
