COOKWARE THAT’S BEST WASHED IN THE SINK

Wooden utensils – The hot temperatures can cause the wood to warp Vintage plates – Dainty paintwork can become chipped Crystal bowls and glasses – Can get cracked or dulled in the machine

Good quality knives – These can lose their sharpness and nick dishwasher’s plastic interior Insulated mugs – Unless they are dishwasher-friendly, the machine can ruin the insulation

Cast-iron skillets – If you have created a non-stick layer on your pan, the appliance will destroy it Bottles and jars with labels still on – The paper stickers can get stuck in the filter, causing problems Aluminium and copper cookware – High temperatures can cause discoloration in these materials Burnt pans – A dishwasher won’t be able to tackle these tough stains Cheese-graters and garlic presses – A dishwasher struggles to get rid of all the tiny pieces of food
