8 Things You Should Never Ever Put In The Dishwasher

I've hated doing the dishes since I was a young girl and I think my dislike for the chore stems from the fact that I often had to do dishes for a family of six, which is a lot. We had no dishwasher, so everything had to be done by hand.

Years later, when I finally got my own place, the first thing I invested in for the kitchen was a dishwasher, and honestly, I've never been happier.

However, after a few items got ruined, I came to the realization that some dishes and kitchen tools are just not meant for a dishwasher, even if they're labeled as dishwasher-safe.

Here are eight things you should never ever put in the dishwasher:

1. Vintage dinnerware

Grandma's vintage cookware and dinnerware are worth a lot of money these days, so you should be taking care of them even if you don't have sentimental reasons to do so.

The harsh detergents and extremely hot water can strip the coating and hand-painted details from the china and classic glassware, so avoid putting them in the dishwasher.

2. Aluminum cookware

If you'd like to keep your aluminum pots and pans looking good as new, stop cleaning them in the dishwasher. They will become discolored when they come into contact with the dishwashing detergent, many of which are alkaline in nature.

3. Wooden boards and utensils

The chemicals and heat in the dishwasher will end up causing your wooden cutting boards and utensils to warp, lose their shape and smooth finish. Carolyn Forte, the director of the Cleaning Lab at the Good Housekeeping Institute, suggests making a safer cleaning mixture by combining 3/4 cup of beach and one gallon of water.

4. Jars with labels

For the sake of your wallet, always remove labels from jars and other containers before putting them in the dishwasher. If you don't take them off, you run a risk of getting pieces of paper stuck in the filter and heat coils, which usually comes off during the wash cycle. This could lead to some serious problems that cost a lot to repair.

5. Chef Knives

Unless your dishwasher has a separate rack for knives, you should never put knives in it. Not only will it ruin the edges, handles, and color of your fancy knives, you could end up with some serious damage to the interior of the machine.

"The high temperature and moisture of the dishwasher can seriously damage both the steel and the handle," Josh Moses, co-founder of Misen, tells The Kitchn. This is especially true if your blade is carbon steel (more likely to rust) or has a wood handle."

He added, "The water jets in the dishwasher can cause the knife to knock into whatever else you have it in the dishwasher with, and can damage the edge. It's a good way to ruin a knife quickly."

6. Cast iron skillets

Cast iron skillets are one of the best cooking tools to own, but they also require a lot of care. Whether yours came pre-seasoned or you did the job yourself, putting it in the dishwasher will ruin the coating.

The best way to clean a cast iron skillet is by rinsing it with warm water and gently scrubing it with salt to protect the seasoned base.

7. Travel mugs

Keep travel mugs away from the dishwasher if you still want them to continue doing their job properly. The dishwasher will ruin the insulation, which means your drinks will not stay hot or cold for as long as they should.

8. Copper cookware

Like your cast iron skillets and aluminum pots, washing copper cookware in the dishwasher will ruin their gorgeous shiny finish. This holds true for 100% solid copper, unlined copper and stainless steel copper-plated mugs and cookware.

As a general rule of thumb, if a dish or utensil is not labeled as dishwasher-safe and you're hesitant, you should stick to cleaning it by hand.
