The dishwasher is just one of the “best things since sliced bread” creations, saving you hundreds of hours spent stooped over the sink. Maybe among the greatest sections of enjoying a tasty meal in your home is knowing you don’t need to endure there washing every dish, cup, bowl, and mug –your dishwasher will probably manage that pesky job for you. 

However, not all of the cutlery and kitchenware are dishwasher friendly. Not all things made for your kitchen may resist the high temperatures dishwashers need to kill germs and wash efficiently. And a few are too precious to risk being chucked in a gymnasium of different goods. To enhance your cleanup regularly and make certain you don’t break the treasured noodle dish, then here are eight things you shouldn’t install in the dishwasher.

Cast Iron

It requires a lot of attempts to get your cast-iron cookware absolutely seasoned! Do not destroy it (or possibly cause your pan to rust) using the dishwasher for a cleaning shortcut. Do not use dish soap (it might break the seasoning down), and dry completely with a towel.


Nonstick Cookware

Normally, the nonstick coating does not hold up well in the turbulent washer. You may probably exclude things that are tagged “dishwasher-safe” from the producer, but give them another look once they come from this machine to notice any harm.


Kitchen Knives

Putting your knives in the dishwasher is a significant no-no. The detergent will dull a knife blade, frustrating as you slice and dice, and also dangerous, as you are more likely to lose control of a dull knife. Additionally, the warm water and heat from the drying cycle may loosen knives’ handles.


 Aluminum cookware

The very hot water in dishwashers will blot the aluminum’s surface, and unpleasant dishwasher detergents may dull the finish. Even if you don’t care about damaging the looks of flimsy disposable aluminum pie pans, then do not set them into the dishwasher as they can mark nearby things as they go around throughout the washing cycle. On the flip side, some stainless steel cookware may go into the dishwasher. Be sure to look at the manufacturer’s directions and wash the pots and pans nicely if you don’t intend to run the dishwasher instantly.


Crystal and hand-blown glass are sensitive to heat; therefore, placing them in the dishwasher will probably make them cheap –and of course, those powerful detergents will cause them to lose their glow.

Wooden Cutting Boards & Utensils

Wood and dishwashers simply don’t blend. The dishwasher’s warmth may lead to wood warping, and the drying cycle may create it crack. So please keep your wooden cutting boards and utensils from the dishwasher.


Copper Pans

Copper is more likely to tarnish, along the dishwasher’s harsh conditions may ultimately ruin the glow of your lovely copper pans and pots. As they’re generally quite expensive, I think it’s well worth hand-washing them to secure your investment.


Milk Glass

The white color of milk glass makes it a cherished collection bit for quite a few, and it is important to understand how to take care of this substance correctly if you’d like it to last. Milk glass may choose a yellowish tint if placed in the dishwasher many times, so you will want to wash it carefully using a soft cloth and warm water.

Graters and Sieves

Any kitchen instrument with sharp edges shouldn’t be put in the dishwasher. Graters and sieves can nick the vinyl coating on the rust, and racks will start to form.


And if you crowd items with little holes to the dishwasher, it’s tough for the water flow to eliminate all the food particles. Again, handwash for the best outcomes.

Ceramic Pans and Cookware

Ceramic pans and cookware are famous due to their non-invasive cooking surface. The title is a small misnomer since the whole pan isn’t made of ceramic, yet there is merely a ceramic coating bonded to the cookware’s metal. A ceramic coating could be applied to cast iron, aluminum, copper, or stainless steel.


Consistently handwash ceramic cookware. Dishwasher detergents can include bleach and citric acids, which are too unpleasant for the end.

Hollow-Handled Items

Hollow-Handled Items (like steak knives, ice cream scoops) might fall apart due to the dishwasher’s high temperature. This results from the dishwasher melting the glue that holds the two pieces of handled items collectively. Rather, handwash these things to maintain them in tip-top form.


Don’t place mops in the dishwasher. It appears a simple thing to do to place the floor cleaner in the dishwasher. But, dishwasher detergent isn’t intended for all kinds of fabric, such as fabric used on flooring cleaning mops. The detergent may cause the mop to fall apart, which may get the dishwasher away from clogging up.

Bottles With Labels Still on Them

If you would like to maintain your jam jar, then be certain that you remove the paper tag and any glue remnants first — these substances usually come off in the dishwasher. They may get stuck at the filter, resulting in more severe issues later (issues that cost far more to fix than the jam jar is worthwhile ).


Thin Plastic

Dishwashers may get hot enough to melt plastic, particularly thinner or flimsier types. The warmth will probably make the items straightened, permanently preventing the lid from fitting snug again. Despite thicker plastics, for example, Tupperware containers, it’s sensible to make sure that they’re tagged dishwasher-safe before placing them through a wash cycle.

Thin Plastics

Additionally, it is sensible to place all plastic dishes on the top shelf of your dishwasher. The best rack is generally farther away from the heating element, minimizing the danger of harm to plastic things.

Hand-Painted Glass and China

Do not Wash Hand-Painted Glass and China in Dishwasher.


Neither the delicate hand-painted layouts on the heirloom china your grandma gave one as a wedding present nor the golden filigree in your special-occasion dessert eyeglasses can withstand the heat and harsh detergent of a dishwasher. To maintain these precious, delicate bits looking good, wash them in soft dishwashing liquid, then wash them off with a dishtowel.

Can I Wash an Instant Pot Lid in the Dishwasher?

Yes, you can certainly wash your Instant pot lid in the dishwasher. In fact, the dishwasher is a great way to get your instant pot lid and instant pot seal clean. Obviously, an air fryer lid can’t be placed in the dishwasher as it has electrical components but the Instant pot lid is designed to be submerged and can be washed in a normal sink or your dishwasher.

Don’t Forget!

Please keep all of your dishes in a pristine state by ensuring they’re dishwasher safe before adhering through a wash cycle. It’s typically much better to be secure with delicate items, like china and precious metals, but if in doubt, you may always check the manufacturer’s directions about the best way to wash items properly.

Besides ensuring that your dishes are dishwasher-safe, it is sensible to provide all items a fast pre-wash until you put them through a wash cycle.

If something isn’t listed above, if you have any questions about whether you need to clean something on your dishwasher, trust your instincts and then clean it.
