Did you know that dish sponges are one of the dirtiest things in your kitchen? Due to the constant exposure to moisture and food residue, even a new kitchen sponge quickly becomes a comfortable place for numerous bacteria and germs. That's why we looked at the question of how often you should really change your kitchen sponges. We have the answer ready.
Be honest: when was the last time you replaced your dishwashing sponge? And the time before that? If this last happened two weeks ago or even more, then you should urgently change something. The maximum useful life of a kitchen sponge should not exceed one week.
If you don't change your kitchen sponges, they become germ-spreaders
In an eye-opening study from 2017, German researchers from Justus University Giessen found that used sponges can collect up to 54 billion bacteria and germs per cubic centimeter. Fortunately, while many of these bacteria were harmless to humans, the study also found some species of Salmonella and Escherichia coli that can cause foodborne illness. So what can you do to have clean dishes without risking your health? Here are some options.
Clean the kitchen sponge daily
To prevent your kitchen sponge from becoming a bacteria carrier, you should rinse it thoroughly with water and wring it out completely after each wash. Never place the sponge in a damp place! Instead, find a clean and dry place next to the sink and lay it out to dry.
To eliminate the bacteria from your reusable kitchen sponges, you can also either microwave them orclean in the dishwasher. Almost 100% of bacteria are killed in these kitchen appliances. This is how it works:
- In the microwave:Moisten the sponge thoroughly and soak it in for about 1 minute.Important!Never put the sponge dry in the microwave as it could catch fire!
- In the dishwasher:Place the kitchen sponge in the top compartment of the dishwasher and clean it along with the dishes with the drying program turned on.
Please note:These cleaning methods will only reduce bacteria counts for a short time. Researchers even found that in some cases, cleaning attempts led to more bacteria forming. That's why you should change your kitchen sponges often, despite regular cleaning.
When is it time for a new dishwashing sponge?
While rinsing and wringing sponges are good habits, even a sponge cleaned so often can collect bacteria over time. Therefore, replace itevery weekto achieve an optimalHygiene in the kitchento keep.
Also, instead of using the same sponge for washing and wiping dishes, it is better to use different sponges for different tasks. This way you can avoid contamination too quickly.
Bonus-Tipp:Have you ever wondered why the kitchen sponges in a pack are different colors? In fact, this is a decision of the manufacturer, but can be for onebetter organized householdbe used. Since kitchen sponges are also used to clean other areas and surfaces, you can decide for yourself which color represents which area. For example, if you choose yellow dishwashing sponges, then only use them to wash the dishes. Then choose a different color to wipe the countertops and hob.
Change kitchen sponges before they smell
If a dishwashing sponge is used for a long time, it may develop an odor and even fall apart. If the sponge already stinks, then you have missed the right time to replace it. The smell is a clear sign that the dishwashing sponge has already become a paradise for bacteria and germs. So change smelly kitchen sponges straight away!
What else can you do?
Traditional sponges are not the only way to wash dishes and clean the kitchen. Instead of the classic dishwashing sponge, you can also use another cleaning tool.
Changing kitchen sponges every week isn't ecological at all, is it? A popular alternative is eco-friendly sponge cloths, which are much more sustainable. They can be washed in both the dishwasher and washing machine at 60°C, which kills bacteria and germs. Furthermore, such sponges are usually biodegradable and can also be put in theDispose of organic waste bin. Tip: Don't wait too long to wash these sponge cloths either. Even after a few uses, they need the wash cycle so that the harmful microorganisms don't have enough time to multiply.
Special cotton dishcloths also offer a more environmentally friendly alternative to the classic sponge. They work just as well at removing stubborn food residue, but are significantly more durable and hard-wearing. You can wash a cotton dishcloth after a few uses at 60°C, then let it air dry and it will look like new again.
If you don't yet own a dishwasher, you can also invest in the kitchen appliance. Washing dishes by hand is not only more laborious, but also uses significantly more water than using a dishwasher.
