What did you put in the dishwasher which the manufacturer said to hand wash?

I'll start by telling you what prompted me to post this thread. My wonderful, amazing husband whom I love dearly put my Vitamix container in the dishwasher, a big no-no according to the company. It still works but it always looks dirty, no matter how much I scrub it (by hand, of course). I have long since forgiven DH, but I am reminded of his misdeed whenever I use my Vitamix, which is often several times a day.

What have you put in the dishwasher against the company's guidelines? How did it turn out?

  1. Mr. Sueatmo has put in cooking implements with black handles, which I prefer not to go through the dishwasher. I have an old cooking fork with a shrunken, wooden handle and very loose rivets that I wish I had never put into the dishwasher.

    I would never put polycarbonate in the DW because I would be concerned with etching.

    1. My husband thinks hand wash only labels/recommendations exist only to create for work him. (he is the clean up crew) He puts EVERYTHING in the dishwasher. If I feel strongly about any particular item, I carry it out of the kitchen, into the laundry room and hand wash it later.

      The dishwasher hasn't ruined anything yet. Many a wine gless was "de-based" due to lack of top rack clearance but wine glasses have short lives in our house even via hand washing.

        Are you talking about your husband or mine? Ha! Ha!

              Ah, polygamy, thy name is dishwashing...

        1. re: cleobeach

          Mine is so afraid of loading the DW incorrectly (I have standards, don't judge!) that he washes everything but plates, glasses, cups and flatware by hand. To his credit, he's learned by watching. I put NO plastic or polycarbonate in the DW, except the bowl and lid of my Cuisinart Mini-Prep, which are surprisingly unscathed after years of DW cleaning.

          I've just melted, warped and otherwise damaged too many items over the years to take chances.

          Now my mother's another story. She'll put ANYTHING that fits into my DW, so I've learned to check her work, as it were. Please don't get me started on the number of snap lock plastic containers she's ruined in the microwave.

        2. I will occasionally put my bamboo cooking utensils if I left them sitting in food or water too long. I figure it is better to put in DW and shorten their life a little than to throw them away because who knows what might be growing in them.

            Bamboo has inherent antibacterial priority.

            If there are, in fact, bacteria or mold growing inside your bamboo utensils, then I don't think dishwasher is the most effective way for disinfection.

            Here are two alternatives which I think to be more effective:

            a) wipe or spray disinfectant liquids at the bamboo utensils. This includes diluted bleach, hydrogen peroxide, white vinegar...etc.

            b) microwave your utensils

              Thanks Chemicalkinetics. I didn't know that about bamboo. I have not been aware of any actual contamination, more of an ick factor. I will try your tips if needed.

              1. re: Chemicalkinetics

                I would throw something away before spraying it with bleach ;)

                I have put pots and pans that hint it would be much better not to use the dishwasher in it. If it's a functional item like that, I won't buy it if the instructions say not to use the dishwasher.

                The only things I'm willing to baby are glass, crystal, vintage dinnerware, silver, vintage Pyrex with fired-on color or decals, etc. Anything meant to be a workhorse had better saddle up and ride on into the dishwasher.

                Oh, I do hand wash my wooden cutting boards, but I also favor using the plastic ones. The wooden ones were all gifts; I bought the wooden pastry board, but it doesn't get washed at all, it gets scraped and oiled.

                  1. re: Chemicalkinetics

                    There is no chlorine bleach in my house, hasn't been for years. I do have color-safe bleach. In case of emergency, my cleaners does this week-long soak in oxygen bleach solution that so far, has rescued everything (typically household items that have mildewed).

                    If a board is unfinished, sanding it would be another option.

                    I rarely put meat on a cutting board. Instead, I have numerous pairs of shears, and if I need to cut something, I hold it, I cut it, the shears go in the dishwasher & I wash my hands.

                1. re: Chemicalkinetics

                  i'd be concerned about those disinfectants being absorbed by the wood or bamboo. if you don't use the heat cycle they really don't get damaged.

              2. " My wonderful, amazing husband whom I love dearly put my Vitamix container in the dishwasher, a big no-no according to the company. It still works but it always looks dirty, no matter how much I scrub it (by hand, of course)."

                When I saw the thread title, I was actually coming into the thread to say that I put my vitamix into the dishwasher all the time. Mine still looks as new as the day I bought it though.

                  I think, we all know, the fault lies in the person who bought the dishwasher detergent. Dishwasher (with water and temperature) alone won't damage the plastic. The detergent, however, is the culprit. Dishwasher detergent ranges from normal to very aggressive. If you pick a very aggressive one, then it will damage for certain cookware.

                  1. re: Chemicalkinetics

                    How do you know which types are "aggressive." Do you check the ingredient list? Is there an ingredient list?

                    1. re: Chemicalkinetics

                      In my area it is not detergent that etches glassware, it is hard water. We have very hard water being in a limestone belt.

                      Since I am not using lead crystal every day (lead softens the glass by the way) I have put it in the dishwasher and the same with sterling, but not the knives, it is bad for the cement that fastens the blade to the handle.

                        <We have very hard water being in a limestone belt.>

                        The moment I read that I said to myself: Not Indiana, is it? Then I read your profile, and see you are from Indiana, and Bloomington too. I just went to visit my friend in Bloomington, IN late last year. It was fun. I went to the state museum in Indianapolis where I learned about your limestone. :P

                        1. re: Chemicalkinetics

                          We live here now but not much longer. We came for one more degree back in 81. Time to move to Savannah. Hope you enjoyed the visit.

                  2. I put a hard-anodized aluminum skillet in once. Didn't do it any harm that I could see, but later I read that it's not a good idea.

                    Maybe the detergent I use has something to do with this. It's Trader Joe's Next to Godliness detergent powder, green in the packaging and green by nature (I think). Gets the dishes etc. clean without attacking them. :-)

                      The instructions on my Calphalon hard anodized cookware, which is all over 20 years old, said to not subject it to the harsh chemicals of the dishwasher, instead you should use Ajax and a green scrubbie (?!?!?!?!?). Since then. solid and most liquid DW detergents have substituted enzymes for bleach, according to Consumer's Reports. I've run across DW detergents that laid down a horrible haze on everything. but not all. It's kind of freakish, in that i've been using the same brand of solids (Cascade), different formulaitons, and the difference is night and day.Currently the one I use has yellow and orange liquid swirls that works well, whereas the one with blue swirls has basically wrecked a bunch of my glassware and black plastic spatulas with the white haze.
