KitchenAid mixer attachments + dishwasher = ruined?

  • 27
  • Share

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.

            1. OK, I guess It appears not as bad as I thought, I found something in the kitchen aid forums and people use barkeeper friends to re-polish it. I did and it seems the rubbing off is minimal after barkeepr's. It seems just like another aluminum utensil now. I found out KA call these "burnished" but they are really not clear coated, only polished make it easy to clean I am not able to get it as silverish shiny as the factory condition, but I will get out my buffing supplies when I get a chance.

              I would never put it in the dishwasher again.

                I can confirm that Barkeeper's Friend cleaner definitely works to remove the aluminum oxide from a KitchenAid whisk. Now, we just need to remember not to put it back in the d/w

              2. Have at it with a Brillo or SOS pad. Have revived Aluminum sheet pans and measuring cups this way. They immediately look shiny and new.

                1. With all of these other replies, I would have thought someone actually knew what they were talking about. They all sound just so authoritative and convincing. :-\..We have a large aluminum pot that was thrown into the dishwasher with the same horrible results. Black and Gray spots, and oxidized gray film/dusty surface. We were horrified as it is quite large and expensive to replace. We tried all of the "remidies" listed here, all to no avail! Barkeepers friend, vinegar and salt, vinegar and baking soda, S. O. S pads, you name it we tried it! NO LUCK! Maybe because of it being such a large surface, it didn't look much better than when we started the whole fix it process.
                  Then it occurred to me, that we had a Mini Cooper with cast aluminum rims that was difficult to keep looking Shiney and new with all that brake dust and street grime from driving. Low and behold, we had picked up from an auto parts store (some time ago) some cast aluminum wheel cleaner (highly acidic so rubber gloves are recommended) and it was in the trunk. It worked well for the wheels, so what's the difference between wheels and a pot?
                  We thought that with all else failing so miserably we just couldn't go wrong just to try one more thing before we "gave up the ghost" - so to speak!
                  So we started on one small spot, spraying carefully to avoid coating a large area, then started scrubbing with the S. O. S pad, making sure to stay in a small 6 inch area. After scrubbing to make sure and rinse the area being worked on, to remove the acid and delete it so it couldn't spread and make matters worse if it failed.
                  Voila! It worked. The area we worked on was all Shiney and new again, and probably better looking than when we first bought the pot! :-)
                  We continued working on the pot, 6 inch squares at a time, both inside and out. And I can tell you this, that no one can tell that there was ever any stupidity on our part for jamming that pot into the dishwasher in the first place.
                  Lesson learned! No aluminum in the dishwasher ever again! :-D

                    Awesome post!! You probably helped out a whole lot of people with this info.

                    1. re: flourgirl

                      Thanks flourgirl! :-D That indeed was my hope, it certainly helped that I was desperate enough to try anything at that point.
                      After you are done with the aluminum wheel cleaner, please make certain to clean the item(s) very well with dish soap and water, as I wouldn't want any residue left behind to poison anyone. But this goes without saying, of course! :-)

                      1. re: flourgirl

                        By the way, that should have read delute it, NOT delete it. Sorry for the typo! The sentence below is where the typo appears.

                        After scrubbing to make sure and rinse the area being worked on, to remove the acid and delete it so it couldn't spread and make matters worse if it failed.

                    2. Soak in a solution of white vinegar for at least a couple of days should make subsequent cleaning easier.

                      1. The problem is that KA likes to use CHEAP ALUMINUM to make their mixer paddles. These will always oxidize, regardless of how you care for them. If you're a conscientious chef, and you don't want to feed your diners oxidized Aluminum in their food, either use the plastic coated attachments or find a company that makes these out of STAINLESS STEEL.

                        1. I just soaked mine in some TarnX for a few minutes. It is not as shiny as when new, but it goes on and off much easier now.

                          1. The black that is rubbing off is aluminum oxide. Don't worry about it because any uncoated aluminum will do that.

                            Id hand wash them in the future because the harsh detergents aren't good for them but they certainly aren't ruined.

                            1. I had the same thing happen, the black corrosion came off on my fingers and left black stuff in my bread dough. It tastes metallic and bitter. Besides using Cascade, I had been storing them in a cute vintage cast aluminum pot on my counter.
                              I don't want to use them so I tossed them and found replacements,

                              1. I just found this post because this just happened to me. Both my paddle and my dough hook. I don't care about looks, but that stuff rubs off into the dough!!!

                                I just wiped it off with a paper towel, but am going to look into some of these remedies and quit putting them in the dishwasher.

                                1. Just remember the problem with using a steel wool pad like Brillo or SOS will leave steel particles in the porous aluminum and sooner or later will cause rust spots on the utensil

                                  1. After cleaning it with vinegar and baking soda to remove all black just polish it with steel wool and rub with vegetable oil... Happened to mine and hubby fixed them :@)

                                    1. Mr. Clean Magic Eraser............took care of the gunk in 3 minutes. Now to keep it off!
