Tarnished Pewter
Remove tarnish with a commercial pewter polish or a
paste made of rottenstone and boiled linseed oil or olive
oil. After cleaning, wash in hot, soapy water and rinse
with hot water. Dry by rubbing in one direction until no
black comes off on the cloth. Complete buffing is
necessary for a shine that lasts. Fingerprints are
hazardous to old pewter pieces if touched before
completely dry.
