    I've got a 30 year old cornet with stainless valves (casings and ports) and they're still bright and new. I think these're nickel but Ed may be right about it being a deposit..backed up by what tptr 1 says. Send the pics to Brett...

    PS I use an orthodontic paste to clean insertion marks on my mouthpieces all the time. Be careful on valves though.

    I think "rust' is an inaccurate term. I'm not sure, but I think the word rust only applies to oxidation on steel. I can't see the pics on my machine, but I can guess what they look like. It very well could be what Toots said... an buildup from the parafin base of the Cass oil. Or it could be what is called "gauling". That happens when the allow in the valve has too much tin in it. That causes it to pick up brass from the valv casing, turning parts of it a greenish brown. You can polish that off also using toothpaste or lava soap.

    Ha. Good one, Toots. Spelling isn't my strong suit.

    Mike (and anyone else).. if you want to see his pictures, do a right click and then copy the properties for each picture. Paste that link into the address bar and "voila" (another French word), the photo will appear. It'll also show up on the original post after that.
