A couple of teaspoons per cup of vinegar should do it. It's not critical.

As I understand it, there are two basic types of cleaners on the market -- abrasive and non-abrasive. The abrasive cleaners, such as rubbing compounds, etc., actually remove minute amounts of metal. The non-abrasive compounds either convert the oxides back to pure metal or remove a microscopic amount of the metal. The vinegar and salt method should not remove any metal at all.
Mike Brazill recommends Flitz, because it cleans well, removes a negligible amount of metal, if any, and applies a wax coating that protects the metal from tarnishing. If you are polishing by hand, it would take thousands of applications of polish to remove a significant amount of metal; however, if you are using a buffing wheel and a fairly aggressive polish, such as emery, you can injure the metal.

If you used a different acid, such as concentrated hydrochloric acid, the results would be entirely different. Posted: Jun 25, 2009 3:00pm Bri: Why don't you send an e-mail to Flitz to find out where you can get the stuff in the UK. There may be similar chemicals available in the UK or in the EU.

Thanks, Bill, I will. I'll post here if / when I get a response to help anyone else in the UK.

There is a polish made in Germany called Simichrome that is very similar to Flitz. Not as much wax in it, though.

I purchased a container of Bar Keepers Friend last night at the grocery store. This particular product was made for cleaning and polishing stainless steel and copper. It did an amazing job on my copper Benson Bowl. Looks brand new. It is not abrasive, and the entire process took about 5 minutes.

In the case of ketchup and tobasco sauce, the primary thing that helps with removing patina is vinegar (and the mild acid in tomatoes). Bill's advice re: vinegsr and salt is spot on, and I have found (through Master Payne as I recall) that lemon juice and salt also works excepyionally well. Barkeepers Friend, mentioned here as well, or its close companion Bon Ami, are mildly abrasive but will help with stubborn crud or dirt but should be used sparingly.
