Instead, use one half of a lemon (you can squeeze out the juice) and rub it on the inside of the vessel. Allow it to stand for a few minutes and then wash off with plain water. Alternatively you could also try using baking soda with water. Use this mixture to coat the inside of the vessel and allow it to stand for a few minutes and rinse away the excess baking soda.
