The dishwashing machine is becoming essential in our kitchens! In addition to limiting our water consumption, this household appliance makes our daily lives easier by saving us time. It allows you to wash dishes and an assortment of other everyday objects in no time, not to mention that you can also cook up some delicious meals in it. Simply slide in your tablets, your rinse aid if necessary and start the wash cycle: it does all the rest of the work! However, certain materials do not support this machine which therefore has some limits. So, you should be careful not to wash anything and everything in it at the risk of damaging your utensils, cutlery or plates even if it saves a little elbow grease and time. Here are these things to never put in the dishwasher.
1) Distrust of glasses
Both crystal and blown glass are very resistant to the heat that reigns in this device associated with strong abrasive pressure, but this concerns all glasses in general. Dirt is therefore replaced by scratches and white deposits linked to the hardness of the water if you have not installed a water softener. Once the white marks and scratches have set in, you can always try to recover your dishes with white vinegar. However, these efforts are most often in vain! Better to wash by hand and wipe well against limescale.
2) Aluminum kitchen items
From disposable plates to pots and pans to baking trays, not all aluminum accessories are anodized, and that’s why it’s best never to put them there even if the label states that the utensil is made of aluminum. question is “dishwasher safe”. The detergent used risks being too aggressive, because it is too alkaline. This will then cause corrosion which will dull, darken and damage the coating.
Good to know: Your thermoses are in the same boat, their insulation layer can decompose. Be sure to read the packaging carefully before washing.
3) Your good chef’s knives
If you want to preserve the sharpness of your chef’s or hollow-handled knives, avoid putting them in the dishwasher. This will only have the effect of wearing them out and blunting them more quickly where others can become deformed. You should always wash a quality knife by hand!
4) Graduated accessories
This is a lesson learned “the hard way” after an afternoon of baking… Unfortunately, you should never put them in the dishwasher, because the writing will erase, especially on plastic. After two washes, your measuring cups will no longer measure anything at all!
5) Non-stick pans and saucepans + cast iron pans
Dishwashing damages the adhesive coating on your pots and pans. The food ends up sticking, and that’s not what we want! As for cast iron pans, you should never put them in the dishwasher either. In fact, this will make them rust prematurely and make them lose their properties. Your stove will be good for the trash…
