Staub 7 qt Cocotte- white stains after washing?!?

s
Staubfan Nov 4, 2012 04:14 PM

Hello all-

I purchased this Staub back in February. It hasn't gotten a ton of use (maybe 8-10 times) but the last several times I've used it, after it gets washed in simple dishsoap and water, it dries with most of the bottom (but nowhere else) having a white-ish stain to it. This is my first Staub, I can't assume this is how they are supposed to look, but does anyone have any ideas as to what could cause it?

I thought it may be the water so tonight when I washed it I used water from our water cooler system, the "stain" still showed once it was immediately (as always) towel-dryed and allowed to sit in the open air.

Any help would be greatly appreciated. Thanks in advance

    Staubfan,

    It could be caused by a few things. It could be the fact that you have hard water. It could be the food has heavy salt or mineral, and it was cooked onto the pot. I could ask what have you cooked before, but I guess it really does not matter at this point.

    Regardless, you should able to remove the stain using an acidic solution. If you have Bar Keepers Friend, then use it as directed. Mix it with water and use a brush or sponge to clean the pot:

    If you don't have Bar Keepers Friend, then use white distilled vinegar. Pour enough vinegar just to cover the bottom. Heat the vinegar on the stovetop. Then use the dish washer brush or sponge to clean the pot with the warm vinegar. Dump the vinegar. Now, rinse it with water.

      Thanks Chemicalkinetics...

      Chili, pork shoulder braise, frying... so there has been a mix. I thought about the water, but thought the (hopefully) clean water from our water jugs would show if that was true. The "stain" still appeared.

      I do have BarKeepers friend and should have asked if that was safe for the enamel. Without it, my stainless cookware would never be the same. I will give it a try. Thanks again

      Anyone else have this experience?

        <clean water from our water jugs would show if that was true>

        It actually does not necessary rule out this option. If the salts and mineral from the previous water have cooked and settled onto the pot, then the new clean water will have difficultly removing it. In other words, what you have been seeing could be from the previous hard water -- regardless that you are using a softer water now. Nevertheless, if I have to guess, I think it is from the foods (likely the beans and not the pork) and not from the water -- but that is only a guess.

        <should have asked if that was safe for the enamel>

        Yes, and no. If you dissolve Bar Keeper Friend in water and use it, then it is safe for the enamel. If you use Bar Keeper Friend dry, then it is possible that you can make light scratches. Even then, it would be very light scratches.

        Good luck, and let us know if the problem persists.

          Thanks again-

          I actually have the liquid BKF. The foods could very well be the reason, as could the water I suppose. If throwing in a little BKF now and then keeps it clean, then so be it. As mentioned, it gets frequent use on my stainless stuff.

          Perhaps I will use BKF, then use and wash with clean water, cooking a neutral-ish food (maybe just blanch some veggies) and see if I can narrow it down.

          I appreciate the help.

            My slow cookers does this sometimes. The inserts are black and I often get the white on the sides. Vinegar does help get it off.
