Not every person admits that at his house the sponge changes only about two times a month. In some families, the sponge changes only as it “wears”, but this, as it turns out, is not at all hygienic.
Dish sponge is one of the “dirtiest” things in the house, despite its constant contact with detergent, soda and vinegar. As the analysis showed, ordinary sponges are dirtier by 200,000 times, compared to the toilet seat! During use, a large number of bacteria accumulate in the sponge, which simply do not have time to "wash out" from it completely. Given the fact that one sponge in the family can be used for washing dishes, and stoves, and microwave, and the table, and even the cat's bowl, it is not surprising that microbes accumulate in it quickly. Experts advise change a sponge once a week.
That is why it is better to use several sponges, which, preferably, will lie in different places. If you wash the dishes with the same sponge and at the same time wipe the stove, the table, sometimes wipe the stains from the floor, etc., you should stock up with another sponge from which you can cut a corner. So you will not get confused exactly which sponge serves for what purposes (different colors of sponges do not always help, either). Similarly, you can do with sponges, which are no longer suitable for washing dishes, but can easily be used in cleaning. The cut corner is a distinctive sign that this sponge can be used to clean the kitchen or wash the pet bowls, but not to wash your dishes.
