To polish copper, first remove the tarnish with lemon and salt or a vinegar and salt paste, rinse and dry completely, then buff with a dry, soft cotton cloth in small circles. For a mirror finish, follow with a copper polish cream and a clean microfibre cloth. Polish only the copper outside; never polish the tin lining inside cookware.
Cleaning and polishing are two steps
Cleaning removes tarnish; polishing brings up the shine. Buffing tarnished copper does little until the oxide layer is gone. For dark, oxidized pieces start with how to remove oxidation from copper.
How to make copper shiny again at home
- Clean: rub with half a lemon dipped in salt, or leave a paste of white vinegar, salt and flour on for 15–20 minutes. Baking soda mixed with lemon juice works on light tarnish.
- Rinse and dry: rinse well with warm water and dry completely. Wet copper spots instead of shining.
- Buff: rub with a dry cotton or microfibre cloth in small circles. This is where most of the shine comes from.
How to polish copper to a mirror finish
Household acids clean copper but leave a soft, warm glow rather than a mirror. For a mirror finish, clean first, then work a small amount of copper polish cream over the dry surface with a soft cloth, let it haze, and buff it off with a clean microfibre cloth. Polish cream contains a very fine abrasive, so use it on the outside only and do not repeat it every week; each polish removes a little metal.
Copper polish options compared
| Polish | Result | Note |
|---|---|---|
| Lemon and salt | Warm, natural shine | Quick, for light tarnish |
| Vinegar, salt and flour | Good shine after heavy tarnish | Needs contact time |
| Baking soda and lemon | Gentle clean | For light tarnish |
| Tomato ketchup | Good on hammered and engraved copper | Gets into dents |
| Copper polish cream | Highest, mirror-like shine | Outside only; rinse and buff well |
Polishing copper pots, pans and hammered copper
On pots and pans, polish the outside and the base only; the tin lining inside stays dull grey and is washed with soapy water. On hammered surfaces, move the cloth lightly with the hammer marks rather than pressing into them, and clear paste from the dents with a soft toothbrush. Do not sand the marks smooth; they are the handwork. Trays with engraving have their own guide: how to clean and polish a copper tray.
How to keep copper shiny
- Dry copper after every wash.
- A weekly wipe with a dry cloth slows tarnish noticeably.
- Keep it away from damp cupboards and bathrooms.

Frequently asked questions
How do you make copper shiny again?
Remove the tarnish with lemon and salt or a vinegar paste, rinse, dry completely and buff with a dry cotton cloth. A copper polish cream gives the highest shine.
Can you make copper shiny with vinegar?
Yes. A paste of white vinegar, salt and flour removes tarnish; rinse it off, dry the copper and buff it to bring up the shine.
How do you polish copper to a mirror finish?
Clean off the tarnish first, then apply copper polish cream to the dry surface, let it haze and buff it off with a clean microfibre cloth.
Does the same method work on brass and copper?
Yes. Lemon and salt, vinegar paste and polish cream work on both. Lacquered brass or copper should only be wiped with a damp cloth.
Should you polish the inside of a copper pan?
No. The inside is tin and turns dull grey with use. Polishing it only wears the lining away.
About this guide
This guide was written in the Moda Bakır workshop in Kahramanmaraş, Turkey, where we have been hand-hammering copper trays, pots, pans and coffee pots for around 40 years. Our own craftsman tins our cookware, and re-tins old pieces, with lead-free pure tin. The advice comes from the pieces we make and the ones that come back to us for repair.
