How to Clean Kansa Utensils (Thali, Katori, Glass)
Wash kansa after every meal with mild dish soap and warm water, then dry it straight away with a soft cotton cloth. That’s all daily care needs. Kansa tarnishes more slowly than brass or copper; when it does dull, rub gently with tamarind pulp or lemon and salt, rinse well and dry. No steel wool, no dishwasher, and no leaving it wet.
What kansa is, and why it needs gentler care
Kansa, also called kansya or bell metal, is a bronze: an alloy of copper and tin. It’s the traditional metal for eating thalis and katoris across Odisha, Bengal, Assam and Maharashtra, and it’s hammered or turned and then finished by hand. Many kansa sets, including ours, have a soft matte finish. Aggressive scrubbing or polishing creates shiny streaks on matte kansa, so the goal is gentle, regular care.
Daily care after meals
- Clear. Empty food soon after eating; don’t let sour dishes sit on the thali for hours.
- Wash. Warm water and a drop of mild dish soap, with a soft sponge.
- Rinse. Rinse thoroughly.
- Dry by hand. Dry immediately with a cotton cloth. This one step prevents most spots.
- Store dry. Stack with a cloth between pieces to avoid scratches.
Fixing common kansa problems
| Problem | Likely cause | Gentle fix |
|---|---|---|
| Overall dullness | Normal ageing, water left to dry | Tamarind pulp rubbed along the finish, rinse, dry |
| Dark spots | Water drops or food left on the surface | Lemon dipped in salt on the spot only, then rinse and dry |
| Greenish patches | Stored damp | Baking soda paste for 5–10 minutes, soft brush, rinse, dry fully |
| Sticky oil film | Ghee or oil not fully washed off | Warm soapy water, then a little besan (gram flour) as a gentle scrub |
| White water marks | Hard water | Wipe with diluted vinegar (1:1), rinse, dry |
| Shiny streaks on matte | Over-scrubbing | Rub evenly with a soft cloth and tamarind to blend |
The traditional way: ash, tamarind and besan
Before dish soap, kansa was cleaned with wood ash or rice-husk ash, tamarind and gram flour. All three are mild. Besan cuts oil and ghee without scratching, tamarind lifts tarnish, and fine ash polishes gently. These still work well today, especially besan for the ghee film left after a festive meal.
Monthly polish
Once a month, or before guests, give the set a polish: spread tamarind pulp over each piece, wait 5 minutes, rub in the direction of the finish with the fibres, rinse well and dry. Matte kansa should look evenly soft and golden, not mirror-shiny. If you want a brighter look on a polished piece, buff with a dry cloth after drying.
Avoid: the dishwasher, steel wool, harsh scouring powders, bleach, and soaking overnight. Also don’t store pickles, curd or leftovers in kansa: acid and salt over hours cause dark marks.

Frequently asked questions
How do I clean kansa utensils daily?
Wash with mild soap and warm water after each meal and dry immediately with a cotton cloth.
Are kansa utensils dishwasher safe?
No. Dishwasher detergent and heat dull and discolour kansa. Wash by hand.
How do I remove black spots from a kansa thali?
Rub the spot with lemon dipped in salt or with tamarind pulp, rinse well and dry. For matte kansa, rub along the finish so it stays even.
Does kansa tarnish?
Yes, but more slowly than brass or copper. Drying it after every wash keeps it looking good for years.
Can I use Pitambari or a brass cleaning powder on kansa?
Brass cleaning powders work on kansa, but test on the underside first and avoid hard scrubbing on matte finishes. Rinse thoroughly before eating from it.
