Copper does not rust, but it stains without apparent effort and water makes black spots on it. Soot in moist air reacts with the metal to create a green deposit called ‘verdigris’. Clean off verdigris and dirt by rubbing hard with a paste of powdered chalk and methylated spirits on a soft cloth. Use a fine steel wool on stubborn areas, but beware not to scratch your ageold piece in the process. The final stage of polishing is to use a metal polish – a soft cloth buffing wheel on a power tool gives a deep shine, but over big surfaces, polishing by hand with a soft cloth achieves a finer finish.

Clean a brass antiquate by washing it in detergent, then rubbing it with a solution of 1-heaped tablespoon of salt and 2 tablespoons of vinegar to a pint of water. Clean the old polish and dirt out of engraved brass with a solution of ammonia on a toothbrush, then with detergent and at long last with clean water. Immerse gravely corroded brass in a strong warm solution of washing soda for a hour, then wipe or brush the antiquate piece. If all the corrosion does not come off, repeat the process. Brush the stained constituents with a glass brush, obtainable from a jewellers’ supplier. Rub off spots of corrosion with scouring powder on a cloth or, if they are bad, with fine steel wool. Here, also, one ought to be very careful not to harm the antiquate with exuberant rubbing. If scratches cannot be prevented then polish with a paste of whiting – a finely ground chalk obtainable at DIY shops. Dirty brass handles and fittings on ageold furniture should, if possible, be got rid of before being cleaned. Otherwise, cleaning with polishes and lacquers will surely harm the wood.

Metal polish, a soft cloth and hard rubbing manufacture the best results on both metals and of course, the likelihood of damaging your priceless oldfashioned this way will be significantly reduced. Delicate engravings might be rubbed away using metal polishes so in this case, vegetable oil on a cloth and a great deal of extra rubbing will be a better option to fetch it to a shine. On deeply engraved antiquate pieces, use a medium-soft toothbrush to get metal polish into all parts, then with a soft brush inside a duster to get it out. Finish with a soft cloth.

There is no alternate for the sheen received on copper and brass antiques by regular polishing, but clear lacquer, received from DIY and art shops, saves much of the work. Because lacquer goes cloudy in cold weather and picks up dust in the atmosphere, it ought to be used in a warm dust-free room. Spray or brush the lacquer on to the metal and, if it in the long run starts to crack or break up – acetone will remove it. If an ageold has been mended with soft solder, paint on a coloured lacquer to match or approximate to the true colour of the metal. Do not utilize lacquer to a mended spot if the antiquate is ‘raw’, this will make a more glorious patch that may not match the introductory sheen.

Dents in copper and brass oldfashioned pieces are best got rid of by pressing the metal versus a short length of wood, shaped at one end to fit the curve of the damaged article. Press and rub versus the shaped end until the dent is removed. Hammering is not advisable, though hammering with a ‘planishing’ hammer from the inside versus a leather cushion is a professional method. Fractures in brass and copper antiques may be mended by soft soldering but cast brass is heavy and hard soldering or brazing makes a much better occupation of such joins.
