If you have a dishwasher in your house, you will probably agree with us that it is one of the most desired and loved appliances induce to the enormous and tedious work that it is capable of saving us in the kitchen. Thanks to them we avoid having to spend hours and hours in front of the sink washing the dishes by hand. Once the dishwasher crosses into your life it is impossible not to fall in love with it.

In addition, it is an appliance that is capable of surprising you more every day, since even when you thought that there were certain utensils that you could not put in it, such as the shelves in the fridge or the filters in the extractor hood, you were wrong! ! However, be very careful! In the kitchen we also use some things that should never end up in the dishwasher either for the sake of those things or for the sake of the dishwasher it. We tell you what they are:

Things you should never wash in the dishwasher

Most of the utensils that we are going to show you below are for, so it is very likely that sooner or later you will end up putting them in the dishwasher without realizing it and with all the good intentions in the world. Obviously, these instruments will most likely not be broken when the wash cycle ends and you take them out, but you do have to take into account that their useful life could be seriously reduced if you wash them regularly in the dishwasher.

Do not put knives in the dishwasher

Except for small table knives (those that hardly even cut), kitchen knives should never be washed in the dishwasher, especially those with wooden handles. Avoid washing knives in the dishwasher as the detergents used are usually too aggressive for steel. In addition, dishwashers do not have a special rack or compartment adapted to protect them from knocks during washing.

Be careful putting pressure cooker lids in the dishwasher

You should be careful when putting pressure cooker lids in the dishwasher for two main reasons: First, because the rubbers lose effectiveness. Secondly, because if powder detergents are used, their particles may remain trapped in the valve ducts, even clogging or obstructing it.

Wooden pallets

Wooden instruments are not suitable for the dishwasher as, due to the high temperatures of this appliance when it is running, they risk dissolving or changing their consistency. If you don’t want your popsicles to be reduced to splinters, it’s best to wash them by hand.

Crystal goblets

You may be afraid to wash your precious wine and champagne glasses by hand, but what you don’t know is that by putting them in the dishwasher you are causing them even more damage. High temperatures, time, your wash cycle and proximity to other utensils can cause your materials to end up cracking, chipping and even losing their shine or directly breaking. If you want to wash them properly, follow the following advice: Heat two cups of vinegar and pour them into a basin. Put the crystal glasses inside and let them soak for at least three or four minutes. Then rinse them with clean water and dry them with a lint-free towel to achieve a perfect finish and shine.

Tuppers

Toppers are the best invention of the century to take food to work or to store food in the fridge to consume another day; however, when it comes to putting them in the dishwasher you must be very careful. Unless an item is clearly labeled by the manufacturer as ‘dishwasher safe’ (you can look it up online if you’ve already thrown out the box it came in when you bought it), you shouldn’t put it in the dishwasher if you don’t want a mishap.. The heat from the water or the drying process can melt or change the chemical composition of the container, making it no longer safe to place and reuse food.

Non stick pans

As with Tupperware, unless the manufacturer expressly indicates that they are dishwasher-safe, pans and pots with a non-stick Teflon coating should be washed by hand. During machine washing, the non-stick coating may crack, causing it to gradually come off with use.

Pet feeder

You probably think of your dog or cat as a member of the family, but their. Have you ever heard that story that a dog’s mouth is cleaner than a human’s? Don’t believe it. It is best to wash your pet’s bowls by hand and allow them to air dry.

Jars with paper labels

When we want to reuse a commercial glass jar from which it is difficult to remove the label, it is very easy to be tempted to put it in the dishwasher. Mistake! It is true that at the end of the washing cycle not a trace of the label will remain. The problem? That this could end up clogging the drain. If ever a jar with a label ends up in your dishwasher by mistake, don’t forget to check the drain afterwards to remove the globs of paper that will have been clogging it.
