Examine the chrome for rust spots. You can easily fix them using balled up aluminum foil; just rub it gently over the rust spots and it will make the rust disappear.
Use a clean cloth with LimeAway, vinegar or rubbing alcohol to clean bad spots on the chrome.
Remove the rubber tips on the legs, if possible. This will allow you to clean dirt that might have collected at the top of the rubber tip.
Polish the chrome after it is clean by rubbing baby oil, WD-40, furniture polish or furniture polish on with a clean cloth until it sparkles.
