Can I wash dishes in cold water?

If you don't use soap when washing your hands, washing with warm water is actually more helpful. Above all, greasy dirt is better removed by the higher temperature. The reason for this: hot water has more energy. Fats and water cannot form chemical bonds, but they can still mix. This process is called an emulsion. This requires energy, which supplies warm water.

However, hands, for example, only get really clean when soap comes into play. This is the only way to thoroughly remove a large part of the dirt and pathogens. This is because the soap binds fat and water molecules together. The soap molecules trap the dirt particles. When washed, they are removed together. Pure water is of little use. Time is also crucial. Basically you should wash your hands for at least 30 seconds.

Protection against disease

With the help of soap, most of the germs are removed, so the likelihood of infection is significantly reduced. Before washing your hands, you should touch your face as little as possible. Areas such as the eyes, nose and mouth in particular should be avoided, as pathogens can easily get onto the susceptible mucous membranes. Especially in the cold season, it is important to pay attention to this simple hygiene measure to prevent infection.
When cleaning the house, however, cold is actually better. Most all-purpose cleaners contain alcohol, which evaporates under the influence of heat and thus loses its optimal cleaning power. Even stubborn blood stains can be removed better with cool water. The same applies to dishes as to the hands. The warmer and soapy the water, the cleaner it gets.
