A sponge is intended for cleaning objects. But why sponges often have the opposite effect, as they are full of germs, we explain in the following home tip.
Sponges: Ideal conditions for germs
- The household kitchen sponges in particular are breeding grounds for germs and can sometimes even cause diseases.
- According to studies, the density of bacteria in a sponge can correspond to more than 5 times 1010 cells per cubic centimeter.
- The reason for such a high number is that the pathogens find ideal living conditions in the dishwashing sponges.
- The sponges are mainly made of foam, such as B. Polyurethane. The countless pores create a very large inner surface, which offers the microorganisms plenty of space to multiply.
- Another reason is that the microorganisms in the sponges have a lot of moisture and warmth, which allows the germs to develop optimally.
- In addition, food residues always remain in the sponges. This allows the germs to develop excellently.
- It is important to know that a normal wash, even with hot water, does not do much good. The germs remain in the sponge.
- Scientists recommend not cleaning the kitchen sponges but changing the dishwashing sponge regularly.
