Cleaners by Other Makers
Many commercial brass cleaners do not list constituents, so we can't tell you much about them. We did test several commercial cleaners, and found that Luster was quicker, easier to use, and more effective than any of them.
Also, lots of tips columns for the environmentally concerned recommend things like Worcestershire sauce, lemon juice and salt, ketchup, vinegar, etc., etc. Luster will do the job much more easily than any of these, is just as friendly to the environment, and is odorless.
One thing to watch out for is those that contain petroleum distillates. Petroleum distillates are flammable and do not contribute to the polishing action. They supposedly inhibit re-tarnishing of the surface, but this mixture does not polish very well. Doesn't smell too good, either!
Ammonia is sometimes recommended for cleaning brass. That is, of course, rather unpleasant, and it really doesn't work nearly as well as Luster.
