Caring for Raw Metal Products Over time, your brass and copper accessories will begin to patina. This is totally normal and can be as beautiful as shiny metal. However, if you do not like the look of the aged patina there are simple steps you can follow to keep your pieces looking their best.
Basic cleaning If your brass or copper item is dusty or dirty rather than tarnished, simply wash it with mild soap, rinse well, and pat dry with a soft cloth. Use a toothbrush to gently scrub any topical residues. Let it dry for a few hours before storing.
Tarnish Removal The most efficient way to remove patina from brass and copper is to polish your pieces with 0000 extra fine grade steel wool pad (can be found at any hardware store). Polishing is N/A for german silver. Occasional buffing will bring back shine to oxidized copper pieces. Alternatively you can make a thick paste of lemon juice, salt and baking soda. Use an old paint brush to brush it over the entire surface. Let sit for five minutes. Take a cut lemon and buff the surface with the cut side. Rinse well and dry with a soft cloth. Let the piece dry off completely before storing.
