An ancient way to polish pewter is a cool one. Just get some cabbage leaves and dampen them in vinegar. Then dip the leaves in salt and use them to scrub your pewter clean. Rinse with water and a gentle soap after that, followed by drying with a soft cloth.
Mix 1 cup white vinegar and 1/2 cup white flour to make a paste. If it needs to be abrasive, add 1 tsp salt. Rub circular with microfiber or other soft cloth. Rinse with warm water after 30 minutes.

Hi Jackie, use a solution of warm water and dishwashing liquid to gently remove any dirt from the pewter piece, then rinse it carefully and dry it with a soft cloth. You can also use a mixture of one cup of vinegar and half a cup of flour to clean polished pewter.
Thanks on behalf of Jackie!
