How to remove oxidation from galvanized metal

Is there some combination of vinegar, baking soda, or sulfuric acid or another acid that can be applied to galvanized tin to make it shine as original?

You can use 5% hydrochloric acid (you can add 1 gm gelatin to 1 liter solution). Rinse well! Good luck!
