A tin alloy long appreciated for its durability, pewter doesn’t rust like iron or tarnish like silver. Antique pewter pieces typically contain elevated levels of lead, which darkens with age and results in a special silver to charcoal grayish-black patina. Although most collectors prefer the antiquated appearance of their patina, some like pewter bits to look bright and shiny. Once polished, pewter can retain its shine for many years.
Mix about 1 teaspoon of mild dish soap into two quarts of warm water. Don gloves. Dip a soft cloth or sponge into the process and gently wipe the pewter surfaces free of dust and dirt. Utilize a soft-bristled brush to get into crevices.
Wash the pewter slice with warm, clean water. Thoroughly dry it with a soft, clean cloth, buffing up the shine.
Use a quality all-purpose metal polish to give brightly finished antique pewter bits more shine. Following the instructions on the item’s label, use a generous amount of wax implemented with a very soft fabric. Rub the metal hard employing a circular movement.
Wash the polished slice in warm, soapy water and then rinse it thoroughly. Dry the item by rubbing it in just 1 direction until no more black comes off on the fabric. Duplicate the polishing, washing, rinsing and drying process until the piece reaches the desired level of brightness.
Polish a vintage pewter piece with a dull finish with a mixture containing two tablespoons of rottenstone powder and only enough mineral oil to form a thick paste. Dip a soft, clean cloth into the paste and rub it on the pewter in 1 direction. Wash the piece in warm, soapy water, rinse well and buff it dry until no more black comes off on your own fabric.
