Dishwashers. They could just be the greatest kitchen invention since the corkscrew. A blessing, yes, but these handy, labour-saving devices certainly aren’t a cure-all. We’re here to solve that frustrating First-World challenge of what not to put in the dishwasher.
Anything wood Anything from wooden chopping boards to wooden spoons and wooden-handled scrapers should go straight to the sink. Dishwashers get hot – so hot that the wood can warp and lose its finish.
Vintage plates Whether gifted from your grandmamma or thrifted from your local Vinnies, be wary of exposing antique porcelain to hot water and detergents, which can eat away at any gold plating and hand-painted detailing.
Kitchen knives Chefs never put their expensive knives in the dishwasher: Fact! Dishwasher detergent, which contains highly alkaline compounds, can be very abrasive on their sharp edges and the banging around in the wash cycle can blunt them even more.
Garlic press Anyone who’s used a garlic press knows that it’s tricky to clean. Those hard-to-clean crevices should be tended to by hand.
Baking mats These floppy, thin, reusable plastic mats actually break down over time if you expose them to repeated dishwashing.
Anything insulated Don’t ruin your thermos by putting it in the dishwasher. The double-walled design may be breached by the machine’s heat
Copper pots and pans If you own anything made of copper, make sure you handwash it. Dishwashers can cause them to discolour.
Cast-iron skillets Not only will the dishwasher cause your cast-iron skillet to rust, it will also wash away its seasoning
Some plastics Certain plastic may melt from the cycle’s heat and/or leach toxic nasties like BPA, so only put it in the dishwasher if it says its safe to do so on the container.
Non-stick pots and pans Many non-stick pots and pans claim to be dishwasher safe, but the hot water and harsh detergents aren’t good for the non-stick coating.
Anything with adhesives Avoid putting jars and bottles with labels in your dishwasher. Those small pieces of paper and glue can clog your drain.
Aluminium Dishwasher detergent, due to its strongly alkaline compounds, is also harsh on aluminium finishes, causing it to discolour and turn black.
Anything you’d cry over breaking That heirloom, high-end or particularly delicate china, crystal glassware or silverware you got on your wedding day.
