Use a commercial rust remover, which is usually in powder form, to remove the rust from the dinette table legs. Moisten a sponge slightly and sprinkle a small amount of rust remover on the sponge. Wrap the sponge around the table leg and work the sponge up and down several times until the stain is removed. Repeat for all remaining legs, if necessary.
Cut a piece of aluminum foil with scissors. Use a piece that is big enough to fully envelop the table leg. Squirt a small amount of water on the rust spot with a spray bottle. Crumple the aluminum foil slightly and rub over the rust spot up and down for several strokes. Repeat for any other rust spots.
As a last resort, use a piece of fine steel wool, such as #000, to clean the rust spot. Pour a dollop of oil, such as baby oil, onto the steel wool and rub the rust spot gently several times. Add more oil and use a fresh piece of steel wool for any other rust spots.
Wipe the table leg dry with cloth and apply chrome polish, if necessary.
