Most people don't keep a bottle of tarnish remover or polish under their sink until they need one, but if you need one and don't have time to buy one, a mixture of salt, white vinegar and flour will get the job done too.
The trick is that the salt works as a mild abrasive, and the vinegar is acidic enough to clean off the tarnish and restore your brass fixtures to their former glory. Just blend the ingredients, pour the mix over the fixtures, and let them sit overnight. Then just wash off the mixture and enjoy the results. Have you tried your own homemade polish before?
