Improvised steamer = ring at the bottom of stainless steel pot

kotatsu Jul 13, 2009 06:42 AM

Searched the cookware thread and couldn't find a similar topic, so looking for some help from your collective wisdom. A visiting relative insisted on making lunch, and used a stainless steel pot (inside also stainless steel) to make a steamer. The assembly was a small glass bowl used as a stand to elevate a large glass bowl. We steamed some stuff for about 2 hours by filling the bottom with water and putting on a lid. Unfortunately, I now have a ring at the bottom of the pot, in same size and shape as the small glass bowl that was touching the pan. I used a paste of baking soda + water immediately, but the stain hasn't budged a bit. It seems to resemble a hard water stain.

Any suggestions? CLR? Steel wool? Thanks for your help.

    Vinegar is the secret for cleaning tea kettles and the like. If you ever think it could be mineral deposits, always reach for the vinegar. A second treatment will have it looking like new.

      you guys are the bomb! I let some dilute vinegar sit in the pan overnight, and tah-dah it's gone! There is a super super faint ring, but it's sooooooo much better. Like 90% better. thanks!!!!

        Or maybe CLR.

          kotatsu, baking soda and water makes a basic (pH >7) solution; if that did not work, you might want to try the opposite, a mildly acidic (pH <7) solution, like dilute vinegar.

            Try some BonAmi or similar cleaner. Less abrasive than steel wool.
