10 Items you shouldn't put in the dishwasher
Cast Iron Skillet – all cast iron should be rinsed with warm water, no detergent, otherwise you’re undoing the seasoning.
Wooden utensils and wooden cutting boards – very hot water and heat drying is likely to cause warping.
Vintage crockery – definitely hand wash, dishwasher detergents are too harsh for delicate crockery, particularly gold/silver trim or hand painted work.
Garlic press and graters – best to wash by hand in warm soapy water.
Quality Kitchen Knives – hand wash so as not to blunt the sharp edge.
Silver cutlery – hand wash.
Pots with burnt on bits – the dishwasher won’t cut it. Instead sprinkle a teaspoon of Bleach Complex & Stain Remover (handy in the kitchen as well as the laundry), pour over boiling water, leave it to soak overnight and it should easily wash out by hand in the morning.
Crystal – dishwasher is too risky, hand wash.
Copper pans – dishwasher detergent is likely to dull copper.
Non-stick pots and pans – may lose their non stick quality when washed in the dishwasher.
Keep it ecological in kitchen and food preparation areas. No nasty residues.
