White Hard Water Stains, or Maybe Etching, on Le Creuset Exterior

Jodie Aug 31, 2013 02:05 PM


I have some very, very old blue, and less old flame, Le Creuset. I have been pretty good about washing it by hand but occasionally it has made it through the dishwasher. In addition, we live in an area with very, very hard water. As a result, most of my Le Creuset has nasty white stains on the outside that I can't get off. Sometimes I oil the exterior, and that polishes it but only temporarily. Does anyone have suggestions? Thanks!

    For mild hard water stains, try standard white distilled vinegar.

      This works equally well on your shower head.

      Either distilled white vinegar or lemon juice will work, but I've personally had better luck with 6% citric acid solution. Add 60 g of food-grade citric acid to 1 liter of warm water, mix thoroughly, and put it in a spray bottle. I just used this mixture yesterday to remove some caked-on hard water deposits from a bathroom faucet -- worked great!

        I live in a limestone area and our water is very hard too. I find Barkeeper's Friend to do a good job. Try the vinegar first if you don't have any BKF on hand. You could also try a descaler sold to help with coffee makers and tea kettles.
