Washing machine programs compared: Saving water and energy
The washing machine is one of the most important appliances in the home. Just throw dirty clothes into the drum, add detergent, pour in fabric softener, and set the appropriate program. It turns out that many of us choose a program that consumes huge amounts of water.

We use the washing machine several times a week. Thanks to it, we can enjoy clean, beautifully smelling laundry without needing to wash it by hand. Although the appliance is considered eco-friendly, it depends on which program we use. One of them consumes large amounts of water. Which program are we talking about?
Does the washing machine use a lot of water?
Standard washing machines offer several different programs adapted to different types of fabrics. Each of them is characterized by different temperature settings and spin cycles, which directly impact energy consumption. The more spins, the higher the electricity consumption, similar to higher temperatures.
Most of us use two or three programs. One of the most frequently chosen is the one for washing bedding and towels, as they must be washed at the highest temperature for hygiene. Another popular program is the one designed for dark fabrics, followed by the delicate wash. It might seem that the latter uses the least water, but this is completely different.
Which program uses the most water?
Scientists at Newcastle University have proven that the delicate wash program consumes the most water and energy. The study showed that up to 1.4 million microfibers are released from polyester fabrics during a delicate wash. In comparison, during the use of a standard cotton wash program, about 800,000 microfibers are released. A large amount of fibres is associated with significantly higher water consumption and, consequently, electricity.
Fabrics such as cotton, polyester, nylon, linen, and muslin can be washed at temperatures as low as 40 degrees Celsius, which minimizes the risk of damaging or shrinking the material. However, experts warn against washing at this temperature, because a washing machine set to 40 degrees Celsius uses twice as much energy as at 30 degrees Celsius.
If you want to save electricity and water, wash clothes at 30 degrees Celsius and towels and bedding at 60 degrees Celsius. Consider using mild detergents that are safe for the skin and the environment. You can easily make them at home. Laundry detergent can be replaced with baking soda or washing soda with soap flakes. Fabric softener can be replaced with vinegar with a few drops of your favourite essential oil.
