KitchenAid mixer attachments + dishwasher = ruined?

My wife put all the attachments in the dishwasher, now they are all grey and I think they are ruined. I want to cry! We only used the mixer a few times and we didn't have a dishwasher back then.

Now i remember reading something about this, aluminum + cascade

Do I have to order new ones.. :( dough hook and the attachment black is rubbing off with my hands. I don't know how to find the right one from Amazon, it's the costco HD model.

  1. Try a paste of white vinegar and baking soda.

    I do always put all my kitchenaid stuff in the dishwasher though and I haven't had this issue.

    What attachments specifically? Might help people figure out what could ave gone wrong since there are different materials for some of them.

      they are the silver (burnished) attachments
      when I touch the attachment now, grey color will rub off in my hand, it seems this is corroded aluminum now.

      What would vinegar and baking soda do, one is a base and the other is acid, these 2 things neutralize each other?

      1. re: CACook

        Rubbing the mixture on other aluminum items has helped before. Doesn't hurt to try. Crazier things have happened!

        Just so weird though since my attachments never did this but other things in the same load have.....

    2. No, I mistakenly put mine in there too.. they are grey.. so not so pretty but still work just fine.

        grnidkjun is correct. Aluminum will sometimes come out of the DW a sort of matte grey. But it still does the job just as well. So they are only "ruined" if your focus is on looks and less on performance. Use the "Julia" mindset.... It's your kitchen, and only you need to be pleased with what's in there. What matters is the product, not how the tools happen to look.

      2. Eventually, I bet the black will quit rubbing off (I did the same thing with a meat tenderizer once -- it still occasionally rubs off gray). I've never found a solution that takes if off, but no, baking soda and vinegar probably can't hurt.

        I gotta tell ya, I always observe one cardinal rule: I don't care if it claims it's "dishwasher safe" -- nothing but stainless, glass and ceramic/pottery ever go into my dishwasher. Especially plastic pieces. Sure, it's a lot more convenient to throw your food processor bowls in there, but the heat very subtly warps them every time you do it, and eventually they quit fitting together as they should.

        Another hazard: I once put a "dishwasher safe" plastic bowl through, and the water pressure flung it around and onto the heating element, where it melted into a terrible mess. The dishwasher stunk to high heaven every time it ran for at least a month afterwards.

        My only exception is cheap-ish plastic tools like chopsticks or a pasta scoop, which I'll sometimes throw into the enclosed cage thing at the front of my top rack. They can't get out of it, and it's little lost if something goes wrong with the heat and detergent.

          I haven't had that problem with my processor bowls, or other plastic items for that matter. But I have never used the so-called drying cycle. It's always turned off. So maybe that's the root of the problems you mention.

          I have found that most everything dries just fine if you just let all it sit there for an hour or so (major exception is plastic but even that is no biggie). The residual heat from the washing causes nearly all the remaining water to evaporate right off. No "drying cycle" needed. A quick wipe here and there and you're good to go.

          1. re: johnb

            That's how pretty much every restaurant dishwasher everywhere works. The high temperature of the dishes helps evaporate any clinging water in a matter of minutes. I emulate it at home by popping open the dryer the instant the cycle ends, and it works beautifully.

            1. re: JK Grence the Cosmic Jester

              That's right. Restaurant dishwashers wash at much higher heats than residential DWs, to sanitize in a short time--2-3 minutes. Home machines like mine can also sanitize (mine has a sanitation cycle and is thus NSF certified), but the temp is not as high as a commercial machine so the cycle takes longer. Many or most home machines don't have sanitation cycles with their extra high heat, but the normal heat they put out is generally enough to achieve the "evaporation" effect.

              I sometimes open mine as you do, but generally just leave it alone. It has a vent that opens at the end of the cycle and does more or less the same thing.

        2. not ruined, just oxidized. Try these tips from eHow - Put the piece of aluminum in a plastic dishpan. Add equal parts of white vinegar and boiling water. Let it sit for one hour and rinse it with water. Repeat the process if necessary OR Use Barkeeper's Friend or Copper Glo, available in supermarkets and department stores, to remove aluminum oxide. Rub it into the surface with a wet rag. Wash the aluminum with a mild, nonabrasive detergent. Rinse and dry it with a clean, soft cloth.
          good luck

          1. My KA paddles, etc are plastic coated, so this hasn't happened to them. I have several uncoated sheet pans that have had this happen to them. I switched to not running them in the DW, and I like using them for roasting where they get a seasoning of oil that polymerizes like when you season cast iron.
