A dish sponge is an indispensable part of every kitchen. Even if we use a dishwasher, we often reach for a sponge, which causes this inconspicuous item to become dirty quickly. We often don't realize how much residue remains on its surface.
Studies show that dish sponges are a massive source of germs. Dr. Markus Egert and his team from the university in Furtwangen in the Black Forest thoroughly examined what is on a typical used sponge. The published findings surprised many people.
The sponge is a breeding ground for harmful germs. The numbers can be alarming
The research results were shocking. On one sponge, as many as 82 billion bacteria and 362 different microbes were found, comparable to human feces. As Dr. Egert emphasized, there are few places on Earth like this. A sponge creates an ideal environment for microorganisms because it is moist and warm and contains remnants of substances that bacteria feed on. This should give us pause.

How often to replace a dish sponge? Regularly and often
Most people change their sponge only when they notice significant wear. This is definitely too late—a dirty and soggy sponge means a massive accumulation of bacteria. Specialists recommend replacing the sponge every 2-3 days or at least once a week. It's a matter of hygiene and safety.
If you frequently wash dishes by hand or have many household members, you should do this more often. Otherwise, you risk transferring bacteria from the sponge to other surfaces in the kitchen, which can result in them transferring to food and potentially leading to health problems. Germs can cause very serious food poisoning and illnesses.
Some people try to disinfect the sponge. Unfortunately, washing in the dishwasher, scalding with boiling water, or even microwaving do not eliminate all microorganisms. These are only temporary measures. The safest solution is to replace the sponge regularly.
An interesting aspect of maintaining cleanliness is silicone sponges. They do not accumulate bacteria and do not need to be replaced as often as traditional sponges. However, users note that they are somewhat less effective at removing dirt.
