Kefir as a cleaning agent

What is Kefir ?

Kefir is a fermented milk drink that is made using kefir grains. These grains are a mixture of bacteria and yeasts, which ferment the lactose in milk to produce lactic acid. This fermentation process gives kefir its characteristic tangy flavor and thick, creamy consistency. Kefir is often compared to yogurt, but it has a thinner consistency and a more sour taste. It is known for its probiotic properties, which means it can promote the growth of beneficial bacteria in the body. Some people also use it as a natural remedy to help with digestive problems.

For effective cleaning and disinfection, it is advisable to use appropriate cleaning agents designed for specific surfaces and purposes.
