Few of us use hot enough washing-up water to get dishes really clean. Discover how dishwashers help you blast away harmful germs.
Think about life in a busy household. Three meals a day, plus snacks and spillages, maybe a pet or two, and it’s no wonder we worry about germs in the kitchen. They can hang around in areas that look pretty clean – like in your sink and on dishcloths.
Only water above 60°C cleans dishes properly, but studies* have found that most of us use washing-up water whish is a long way from this temperature. In fact, the studies revealed that some households were washing up in water that was only 27.5°C.
Water inside a dishwasher is heated up to 75°C, which gives you a much more hygienic clean than washing dishes by hand. A fact that’s sure to make you a dishwasher enthusiast.
Hot means clean
Another issue with the hand-hot water we use for washing up is that it doesn’t clean things thoroughly. But again using a dishwasher solves that problem with powerful detergent that can come in the form of powder, liquid or tablets.
Tableware taken fresh from the dishwasher is on average cleaner than that washed in the sink. That’s because the dishwasher uses higher temperatures than our hands can stand – up to 75°C. And because a dishwasher dries everything, there’s no need to use tea towels – which themselves can harbour bacteria.
So that very hot wash, plus the powerful ingredients in modern dishwasher detergents, plus the hands-free drying process add up to one thing: hygienically clean dishes.
