How to keep copper pans clean

[madame]

I have just bought some copper pans but since I have used them they have all water marks over them, and generally look really old and not at all new.

I really need some advice on how to keep them looking reasonable. They work great but just look all smuged and not even and shiny as when I got them.

Any advice on maintenance would be great.

Thank you

anybody out there can you help....

water marks don't matter, it is not dirt, put them in the cupboard and then no-one can see them.

Get some Barkeepers Friend and make up a paste with a little water and polish the pan then rinse well. It will remove the water marks and come up like new.
I have used it on an old copper tea urn that lay in the shed for 20 or so years and it came up beautifully.

tomato ketchup works too

thank you. I will try these.
