Pewter is a soft material that requires careful treatment. We recommend using cotton gloves when handling pewter. Objects that are not being used can be stored in a plastic or felt bag to avoid scratching.

It is generally recommended to avoid using polish on pewter, since it can cause scratches. To remove fingerprints and other stains, rinse the pewter in warm water with a small amount of dish detergent. Dry with a soft cloth. For more advanced cleaning of pewter objects we recommend a professional restorer, for example, KA Johnsson in Stockholm.

Unpolished brass will become darker over time from exposure to air. This change can be beautiful. If the surface is affected by water, grease such as fingerprints or by other corroding substances, it can eventually be damaged and more difficult to polish away. This can happen especially in a humid environment.

Clean the surface with a soft cloth. For a deeper cleaning we recommend a gentle, non-abrasive brass polish. Avoid using brushes, steel wool, polishing cloths, sponges and the like since the surface of brass is sensitive to objects that can scratch. Also avoid lengthy contact with oxides that can cause permanent damage. To avoid water damage, keep surfaces dry with a soft cloth.
