How to clean metal table legs?

Assuming you don't want to use any harsh chemicals or cleaners, one of the best ways to clean metal table legs is to use a mixture of baking soda and vinegar. Simply mix together equal parts baking soda and vinegar, and then use a cloth to scrub the mixture onto the metal legs. You should see dirt and grime start to come off easily. If there are any stubborn spots, you can use an old toothbrush to really get in there and scrub them away. Rinse the legs off with water when you're done, and then dry them with a clean towel.
You can also use this same method to clean other metal furniture and fixtures in your home, like door handles, faucets, and even appliances. Just be sure to rinse everything off thoroughly when you're done so the vinegar doesn't cause any corrosion.
