Hard water, heavy salts and even powder can lead to scale and dirt build-up inside your washing machine over time.
At the same time, when the door is opened, a sharp musty smell appears.
To ensure that the machine works like a clock and does not emit an unpleasant smell, you need to periodically run it for preventive cleaning.
Some housewives prefer to use folk remedies, which work just as well as professional formulations.
For example, citric acid will save you from limescale and unpleasant odor. Pour 100 g of the product into the compartment for washing powder, set the "cotton" mode and start the machine without laundry.
It should be noted that this option is effective if the equipment is cleaned regularly. In advanced cases, citric acid is useless.
In other situations, you can't cope without special means. For example, if the equipment hasn't been cleaned for a year or more, but was used every week.
