After Using Washing Up Liquid
Once you’ve finished washing, always rinse dishes in hot or cold water – always. In the UK, rinsing isn’t really the norm, while across the pond in the United States it’s really quite popular. If you’ve ever seen American kitchens with double sinks, this is why – one sink is used for washing, while the other is used for rinsing. So why is rinsing dishes in cold water so important? Well, there are a number of reasons why you don’t want those soapy residues all over your clean dishes.
First, allowing soap to dry onto your dishes can affect the taste of food and drink – not everyone notices, but those who are more sensitive to different tastes can definitely tell when there’s soap in the mix. Additionally, soap scum can affect the look of glass and crystal, making it look cloudy and smeared. Secondly, rinsing dishes with cold water is better for your health. Many mainstream washing up liquids contain sodium laureth sulphate (or SLS), a chemical found in dishwashing liquids, shampoos, and toothpastes to encourage the soap to foam, helping it to clean better. Unfortunately, SLS is an irritant, which is why shampoo stings when it gets in your eyes. You really don’t want to be eating food that’s covered in SLS, so make sure you wash all those suds off before drying your dishes.
