You might think your dishwashercan handle anything you throw at it.
But while it may be the hero of the kitchen, there are everyday items that simply aren’t built to survive a cycle of high heat, harsh detergents and powerful water jets.
According to appliance experts at Hisense UK, putting the wrong items inside couldleave you with cracked plastics, warped wood or even rusting metal. And the three most common things people mistakenly load into the machine are plastic containers, wooden utensils and stainless steel items.

Plastic food containersIt might feel easy to throw in your lunch Tupperware or leftover containers for a quick wash, but many plastics can’t withstand repeated exposure to a dishwasher’s heat.
Over time, lids can warp, containers can crack and colours fade - leaving them less airtight, less hygienic and far more likely to break.
Wood and water don’t mix well. The intense heat and moisture inside a dishwasher can cause wooden spoons and spatulas to swell, crack and even harbour bacteria in the splits. Before long, your trusty wooden utensils will lose their smooth finish and could become a breeding ground for germs.
Stainless steel and metal-rimmed itemsFrom mixing bowls with a metal edge to stainless steel mugs, the dishwasher’s detergent and hot water can cause deterioration, rusting and discolouration. That shiny metal finish won’t stay sleek for long and once corrosion sets in, it’s impossible to reverse.
While it’s tempting to take shortcuts, experts say a little extra effort at the sink can save you money and protect your kitchenware in the long run. When it comes to items that are dishwasher-safe, choosing the right model can also make a difference.

The Hisense HV693A60UVADUK Integrated Dishwasher includes advanced UV and ion technology, going further than a standard clean by neutralising bacteria and mould for superior hygiene. Its energy-efficient A rating and seven versatile programmes aim to ensure spotless results, protecting your kitchenware.
Chloe Blanchfield, product marketing manager at Hisense, said: "Dishwashers are brilliant for saving time and ensuring hygienic results, but not everything belongs in one.
"Plastic containers, wooden utensils, and metal-rimmed items in particular should always be washed by hand if you want them to stay safe, functional and long-lasting.
"Choosing the right dishwasher model can make all the difference in ensuring all items in the appliance are protected yet cleaned to perfection."
