Brass?

And are you sure they're not meant to have a patina?

I bought them years ago and they were not this tarnished. They were put away for a while and I recently took them back out and would like them to look less dirty.

Try lemon and baking soda, that may work.

I agree, brass. But brass is an alloy of copper and zinc. I would try some commercial copper cleaner, the kind that comes in the little round jars with a sponge.

How about Brasso metal polish?

I'm a fan of barkeeper's friend.

I have used Brasso with success on brass. It took a couple of applications and elbow grease, but I was able to "customize" the amount of clean I wanted and leave some of the patina/tarnish. The birds are very pretty.

So it doesn’t matter, brass or copper?

you can start by trying ketchup.

I tried ketchup, did not work:)”(

I have a lot of brass in my home including door knobs and handles, letterbox, light fittings, candlesticks, etc, and I’ve never seen brass that colour. I think they’re meant to be like that. Could they be bronze?

If they are brass can you get Duraglit wadding in the States? I prefer it to Brasso.

If they are heavy, then they’re probably brass. Even though they would pretty and shiney cleaned up, they might not be as interesting. I don’t know if it’s still around or not, but as a kid, I had the fun job of polishing the brass we had. I’d use something called Twinkle Brass and Copper Cleaner. It’s a paste you wipe on, let dry and then buff off, it works really well. Ace Hardware and Amazon both sell it.
