Projects Need help/advice on cleaning a brass radiator

Ok men, i have a br*** radiator in a bucket and need to know how to get it cleaned and buffed. I may have made a mistake by using Br***o b/c it made it worse.

Thanks for the help in advance

 

i use a product called autosol (napa) its a paste,seems to work o.k.!

 

Thank you sir

 

Flitz should work.

 

I started this one by using a fine sandpaper. The same grit you would use on block sanding a painted topcoat.
Then clean it well and start the buffing with a machine. Start with a co**** and get a finer buff for each time.
Finally you get to a point where it will begin to mirror. Fine dents make this difficult.
