Any tricks to remove corrosion from a finial? The finial on my Oak 30 seems to be comprised of at least a couple of different metals, copper and cast, and it has proved stubborn to corrosion removal. Any ideas? EVAPO-RUST didn't do much.

Ammonia and water. 50/50 mix. Let it sit in a bucket for 15 minutes.

Thanks! I'll try both of those suggestions tomorrow.

Couldn't find the Sno-Bol but I did do a soak in an ammonia, vinegar, EVAPO-RUST combination and it's working but it is taking a considerable soaking. I've got it setting in a five gallon pail and it is slowly coming off. Don't have a canary but the parrot is still alive.

Next question: how to finish the finial?

When I was cleaning mine, someone on here told me to use either Lysol or Clorox toilet bowl cleaner. You have to be careful using this, wear eye and hand protection as it has muriatic acid in it. It worked really well for me and I used a soft tooth brush to get into the crevices. Once cleaned, rinse really well with clear water, then I soaked it in water and baking soda bath to neutralize the acid.

If you like the different colors of the metals the way they are, you could clear coat them with a Thermolux paint. Or, you can send it out for plating, it can have parts brass plated and some nickel. This route would be more costly but would last longer than the clear paint.

After letting it soak for a bit , I'd brush it with a brass tipped wire brush. Helps break down the crap on the finial. Blow it off with compressed air and polish it with mothers polish with a drill and a buffing wheel.

Thanks for the tip, yours looks beautiful. I would have never thought of ammonia to clean mine up but it worked great. I let it soak for about twenty-four hours and it took off everything the EVAPO-RUST wouldn't touch. Now to decide how to finish it off.
