Open a towel on a table and place the silver piece on top of it. Dampen a soft cloth and pour 1 tsp. of silver polish onto it. Place the cloth on top of the silver piece and rub it in a back-and-forth motion, not circular, to remove the existing tarnish from the surface.
Turn the cloth to a clean section frequently and add more silver polish as needed until no tarnish remains on the silver piece.
Hold the silver piece under a stream of running water and rub the object using your fingers to remove all traces of the polish. Apply 1 tsp. of a neutral cleaner to a soft cloth and wash the silver again to ensure removal of the silver polish. Rinse the silver a final time thoroughly.
Dry the silver using a towel until no moisture remains.
Put on disposable gloves and apply 1 to 2 tsp. of acetone to a soft cloth. Wipe all surfaces of the silver with the acetone-soaked rag to degrease it.
Spread newspapers over the work surface and center the silver object on it. Open a can of clear acrylic lacquer and insert a natural bristle paint brush into it.
Paint the lacquer onto the silver in a thin coat until covering all portions. Wait until the lacquer dries and apply a second coat to the silver.
