In this case, no deposit is carried out but the item needs to be acted mechanically upon. With the use of opportune machines, the item is first ground with abrasive belts, and is subsequently brushed and polished with the use of cotton disks and abrasive pastes.

This process can be carried out before a subsequent galvanising treatment in order to obtain a better aesthetic result on the item or otherwise as a final treatment when one wants to confer to the starting material a brilliant shining aspect.

In this second case, a layer of protective transparent varnish is usually applied. If the item is varnished, it can be cleaned with a dry or slightly moist cloth. Avoid using solvents or other chemical products.

Materials which are commonly polished are copper, brass and steel, and they are used particularly in the furnishings sector.
