nothing made of aluminum, it will oxidize and get a grey film on it from the chemicals in the dishwasher detergent

That's a good chair

What about vintage patterned corelle?

That one really made me laugh!!

Or Corningware, Le Creuset, etc.

If you have an HE dishwasher, cut the amount of detergent you use in half. Something is not getting rinsed properly.

You should see the family fights that have happened in my house over my grandmother's Rosenthal china, it's up there with the Hummels. She got crystal from Austria too. We did use it for the holidays and every now and then for nice desserts. But the most I interact with it is washing the dust off 😂

I think it's more about the fact that someone hand painted this, and you just can't find that care put into making an object on a large scale anymore. Things like china are maybe hand stamped now to pass as "hand painted", but someone didn't sit there and lovingly draw that flower on it.

Forgot the vacuum insulated! Dishwashers are perfect at ruining their seals. Add anything with rubber or plastic gaskets and seals to the list to handwash.

For stainless steel to conduct heat, it has an aluminum or copper plate glued to the bottom. Some BIFL brands like All-Clad and some (now harder to find) lines of Calphalon use tri-ply construction where the conductor metal is pressed between the two sheets of steel like a quarter. But aluminum and copper are not dishwasher safe, and the glue used to fuse the plates to the other pan's bottoms will eventually degrade in the dishwasher.

Not that I disagree with anything you said, you seem to know your stuff! It may say dishwasher safe, but it will definitely shorten its lifespan. To get the residue off of my Teflon pans, I've found pouring white vinegar in them and letting that soak overnight usually removes the residues and brings the nonstick quality back.

Same! Except I started earlier when I realized my barber was just putting a #4 blade guard on and shaving straight across the back of my neck. I can do that myself, and have for 25 years now. I see these in thrift shops with accessories and sometimes a case for $5 to $10. What a deal!!!!

Deglaze the pan while it is still hot, I mean adding warm water (don't put cold water in a hot pan or it will warp). That will loosen up the stuck on food, the brown and black bits from searing. Then you should be able to clean it with a dish brush and some liquid soap like Dawn. I also highly recommend making a paste of water and Bar Keeper's Friend or Comet powder if you want to polish them back to looking like new.

I don't know why you got downvoted for simply asking a question. Take my upvote for being curious about how to properly care for your purchases. 🙂

One trick for teflon pans is soaking them in white vinegar every so often. The residues from cooking sprays and soap scum from detergents (even proper ones like Dawn since they removed phosphates), make the non-stick coating less effective over time. I found the vinegar soak brings them back to life sometimes.

Edit: With stainless it really helps to deglaze the pan while it is still hot. Plus Bar Keeper's Friend is great stuff.

It's the harsh detergent, and the blades hit things when the jet sprays them. Seen some knives even get dents and dings on the cutting edge from being put in the dishwasher.

Yeah, anodized aluminum gets that white crust on it from dishwashers. I could always tell how someone ruined their pan when they were returning it to the kitchen store I worked at.

Knives, any pots and pans even if they say dishwasher safe. If you want them to last, hand wash them. It's half the quality of the item, and half how we take care of it.

Plastics should also go on the top shelf only. Heat makes plastic leach. Glass, ceramics, silverware on the bottom, plastics on the top.

I bought a pair of merril trail shoes about 6 years ago that have been my daily driver for that whole time and have had little to no wear and tear

Cascade Complete and multiple higher end Bosch, Whirlpool, and Samsung. I dunno. I taste it on other people’s plastic food ware too. You can even smell it when people at work microwave their lunches in plastic that’s been through the dishwasher. I don’t think it’s just me.

Pattered/colored vintage Pyrex

My coworker claims he washes his unassembled gun in the dishwasher when doing maintenance.

Half the time people clinging to this also refuse to learn the repair methods for modern items.

Especially cars.

Metal straws, usually slips through the grates of the silverware bin

Anything vacuum insulated and anything wood. Everything else goes in.

Sounds like you're using WAY too much detergent or washing them concave side up

Weird, I've been putting anodized aluminum (Circulon) pans in the dishwasher for 15 years with no Ill effects. The pans are still in great condition

I love stainless steel because it goes straight in the dishwasher.

If I didn’t have one then I’d use cast iron and non-stick more, but I love that it’s completely bulletproof. I don’t need to worry about what I’m cooking, how hot I’m getting it, what utensils I’m using, etc. just cook->dishwasher.
