Can This Go Without Saying?

"The toilet brush! I read a story here about somebody that does that regularly."

- BOFHOOC

"That’s disturbing. I had a landlord tell me to put my cat’s litter box in the dishwasher weekly to keep the cat smell down. I did not take her up on that advice."

- annissamazing

"Your toilet brush. My friend found out the hard way her housemate was doing this WHILE DOING THE DISHES."

Apparently... Dinner?

"Fish. I worked apartment maintenance and a lovely old couple ruined, like, three dishwashers in a row by using them to steam fish. Very gross, considering the pre-wash cycle uses the gray water from the last cycle."

"Smelled pretty bad, too."

High-Quality Knives

"I'll admit, we run some knives through, but only the crummy ones. The good ones, NEVER, and ideally those are hand-washed right away after use and not left to sit with anything on them."

Cast Iron Accessories

"I found a La Creuset Dutch Oven on clearance sale at crate and barrel of all places. I immediately bought it. Still, a lot of money to spend, but it was the best purchase I ever made for my kitchen."

"I fully understand why people pass these down from generation to generation. It’s in amazing condition for the number of times I’ve used it. And it’s dishwasher safe!"

"I still hand wash mine, because it’s like a child to me, and I don’t trust my partner to handle it! I always said I’d be a chef if I didn’t love what I do right now. So the fancy kitchen stuff I have always gets hand washed."

"P.S. their website says it’s dishwasher safe, but they recommend a hand wash for longevity and because the enamel can eventually wear down in a dishwasher."

Also, Wooden Kitchen Accessories

"Wooden Cutting boards."

- theSealclubberr

"This is one of my luxuries in life. Using a machine to wash your wooden spoons will shorten their life by a lot. Hand washed and well cared for a wooden spoon will last decades."

"A set of bamboo wooden spoons is like $12, so I buy a new set every year or two. $12 to not hand wash every night? Yes please."

Liquid Dish Soap. Enough Said.

"My daughter did this once, WOW, what a soapy disaster."

- CRCs_Reality

Also, Laundry Detergent

"When I first moved into my own apartment, my mom gave me a sandwich bag full of about a dozen detergent pods as a 'These will help you start off on your own' gesture."

"The first night of living in my own apartment, I fired up the dishwasher. 20 minutes later while playing video games, I noticed this wave of suds moving toward me from the kitchen. When I say a wave, I mean it. I have never seen so many d**n bubbles."

"That’s how I learned my wonderful mom gave me both dishwasher detergent pods AND laundry detergent pods in the same sandwich bag. I had a 50/50 odds and boy did I lose, lmao (laughing my a** off)."

"Needless to say, this happening on my first night living on my own had me questioning what I was doing, and if I would be better off living in my mom’s basement for the rest of eternity."

"Mashed potato residue. Oh my god, it gets on EVERYTHING. Especially if the chunks are too large to fit through the filter. It just sits in the water and coats everything."
