Silver-plated puja items: cleaning them without stripping the plating

Silver-plated thalis, diyas and bowls are a base metal with a thin silver layer on top. Everything you do to them either preserves that layer or removes a little of it. Once the plating is through, no amount of polishing brings it back.

What causes the darkening

Tarnish is a reaction with sulphur compounds in air, and it is accelerated by humidity, by rubber bands, and by contact with certain foods. In coastal and monsoon conditions it happens faster. Darkening is not damage — it sits on the surface.

Safe routine

• Warm water, mild soap, soft cloth. This handles most of it and removes nothing.
• Dry completely before storing. Water left in a diya well is the most common cause of spotting.
• Store wrapped in cotton, not in plastic bags or with rubber bands, which trap moisture and sulphur against the surface.

What wears the plating

Abrasive powders, scouring pads, and toothpaste all work by removing material. They will brighten a piece today and thin the plating each time. Frequent chemical dips do the same more gently but more thoroughly. Keep them for occasional use, not for a weekly clean.

After a puja

Ghee, camphor residue and kumkum should be wiped off the same day rather than left to sit. Warm water lifts ghee; a soft brush reaches the pattern in an embossed thali without scratching it.

A note on what these items are

The pieces we list are described as silver-plated by the supplier, and that is how we describe them. They are not solid silver, and they are not sold as an investment or as hallmarked metal.
