With a minimum of care, pewterware will keep its original finish.
It should be washed in hot, soapy water or in a mild detergent
solution and dried with a soft cloth. If, through neglect, pewter
takes on a patina, the original finish can be restored by polishing
with a non-abrasive metal polish. Dishwashers are not recommended
due to the very high temperatures and rather strong detergents
used.
