Things You Should Never Put in a Dishwasher

There are things that you should never put in a dishwasher. Some people have claimed to put computer keyboards and car parts in the dishwasher to have them cleaned. These people think that if a dishwasher does an efficient job of cleaning the dishes, then it should be capable of cleaning other things too. However, the manufacturers of major dishwasher brands say that putting all kinds of stuff other than dirty dishes and pots in the dishwasher may not be a good idea. Doing so can really affect your dishwasher and the item you want to clean.

Some of the strangest things that people have tried to wash in their dishwashers are baseball caps, shoes, and car engine valves. The guy who put the engine valves in the dishwasher regretted it because his whole car valve set was ruined.

What Can Ruin Your Dishwasher

The dishwasher is mainly designed for cleaning dishes, glasses, pots, silverware, and pans. If you put machine parts or car parts in the dishwasher, the grease can clog the system, which means the water cannot fully circulate. If it is only a partial clog, it still means that the grease just circulates through the wash system, and even wind up on your plates and glasses.

There’s a big possibility that your dishwasher will not last as long. The most common items being placed in the dishwasher, other than the dishes and cookware, are gardening tools, machinery parts, painting tools, and auto parts. All these items can shorten the lifespan of your dishwasher.

Also, your dishwasher can get damaged when there are plastic parts that melt and break off, which can go to the filter. The labels on some of the items can get unglued and clog the washing system, which will definitely damage the dishwasher.

What Items Can Your Dishwasher Ruin

After using the dishwasher, it may retain some food particles and residues from the rinse aid or detergent. If you place a keyboard in the dishwasher, the food particles may end up on your keyboard, or it may end up having bleach spots.

Experts warn that there are certain plastics that shouldn’t be washed in a dishwasher. The heat of the dishwasher can cause the chemicals from the plastics to seep out, which can be risky to the health of everyone. You have to know if the plastic is safe to be washed in a dishwasher, and always place the plastics on the top rack, far from the heat. Also, when washing plastics, don’t choose the dry temperature or higher wash options.

Here are other odd items that should not be placed in a dishwasher:

  1. Bronze and Brass

Bronze or brass items can become discolored if it is placed in a dishwasher because of the high temperature and the strong detergent. This is also true for pewter and copper. The best way to clean them is by hand using mild detergent and water.

  1. Bras

There have been some women who have tried using dishwashers to wash their bra. However, when they use ordinary laundry detergent, it becomes too sudsy, which might cause it to overflow. If you use dishwasher detergents, it contains ingredients that are not ideal for the delicate fabrics of your bra. Plus, the heat of the dishwasher will damage the bra.

  1. Computer Keyboards

The keys may come out clean, but it might still have some water remaining in the keyboard. This is the same as spilling water or soda on your keyboard.

  1. Cast-Iron Pans

Cleaning cast-iron pans and cookware in a dishwasher is a bad idea because it can remove the baked-on oil on the surface called the seasoning. This reasoning forms the slick surface of the cast-iron pan, which is great for cooking and preventing rust. The best way to clean cast-iron pans is to rinse with water or wipe with a clean paper towel.

  1. Fish

The dishwasher is not only used for cleaning odd things, but it is also used for cooking fishes. Some people claim that they cook salmon by wrapping it in foil and heating it in the dishwasher. Manufacturers of dishwashers do not recommend this practice. The heat from the dishwasher may not be enough to kill pathogens in the food, like Salmonella. Also, the temperature is not consistent in the dishwasher as compared to the normal stove.

  1. Knives

It is better to wash the sharp knives by hand, even if it is labeled dishwasher-safe. When putting it in a dishwasher, it can become dull due to the constant rubbing against other cutlery in the basket.

  1. Insulated Mugs

Insulated mugs and travel mugs that are not labeled dishwasher-safe can be damaged if you clean it using the dishwasher. When you place the mug on the normal cycle of the dishwasher, the outer part of the mug is exposed to high temperatures and water, which damages the vacuum seal inside the mug. If the hot water penetrates the mug and gets in the seal, the mug loses its ability to retain heat.

  1. Potatoes

Dishwashers cannot clean the potatoes. The best way to clean them is to rinse the dirt off by hand in the sink.

  1. China with Gold Leaf

Washing your china with gold leaf in the dishwasher is not advisable. The gold can fade or discolor when it is cleaned by the dishwasher.

  1. Wooden Items

Heat, water, and wood are not a good combination. The wood can develop some warping and be cracking when it is constantly exposed to water and heat.
