Common kitchen ingredients come together to help clean the toughest of stains.
Be extra careful while adding baking soda to the vinegar. There is a chemical reaction that takes place which is what helps to remove the stains. My pan was really big, so I did not move my pan from the stove, but I added the soda in small increments.Simmering is recommended for heavily soiled pots/pans.Otherwise you can just leave the baking soda in the hot vinegar water till cool enough to handle. For greasy pots, for e.g. if you made ghee,add a few drops of dishwashing liquid to the boiling water.A good way to do it would be to place your pot/pan in the sink while adding baking soda.This has the added benefit of cleaning the sink drain as well if some of the mixture spills into your sink!
