In Jain Dharma there is no fixed scriptural list of “aushadhi” specially for cleaning silver idols. What is used is decided locally by the temple‑sangh, keeping two main rules in mind:

1. Ahimsa & shuddhi (non‑violence and purity)

- No animal‑based products. - No very strong or burning chemicals (which can damage pratima and are considered ashuddha).

1. Mild, natural, non‑corrosive cleaning

For silver (rajat) idols, most Jain derasars use some form of: - Gunguna pani (lukewarm water) - Halka sa sabun / liquid soap approved by the sangh (very mild, without strong fragrance, and used in very small quantity) - Or a special “rajat‑aushadhi” / “chaandi aushadhi” powder prepared or approved by that derasar, often based on: - Nimbu / citric type ingredients (mild form) - Thodi khadi / baking‑soda type substance in small quantity - Some mild mineral / herbal powder

The exact recipe is usually not public and differs from temple to temple. It is prepared so that: - Silver does not get peeled or pitted. - No sharp acid or industrial chemical is used.

Practical guidance

• There is no one universal Jain aushadhi name for silver; it is not like “ashta‑dravya puja” where dravya are fixed.
• You should follow whatever aushadhi your own derasar or gurudev has approved.
• If you are helping in a derasar and are unsure:

- Ask the pujari / prakshal team: “Yahaan chaandi ki pratima saaf karne ke liye kaunsi aushadhi humko use karni chahiye? Kya koi special powder ya solution mandir dwara tayyar hota hai?” - Do not start using market chemical silver‑polish or strong acid on your own.

Summary: For cleaning a silver Jain idol, traditionally only mild, non‑violent, non‑corrosive aushadhi is used – usually a temple‑approved “silver aushadhi” powder or a very mild solution (water + a little gentle cleansing agent). There is no single standard Jain-scriptural aushadhi name for this; always follow your own derasar’s approved aushadhi and method.
