For an item that'due south supposed to make clean your abode, sponges are surprisingly dingy. Sponges are a convenance ground for bacteria, including Due east. Coli and salmonella since they're typically moist and porous.

While y'all can throw abroad a muddied sponge, some endeavour to avoid waste matter by microwaving it to kill bacteria with heat. Only does this purported cleaning hack actually work?

Read on to learn whether y'all tin actually kill bacteria on a sponge by microwaving. Nosotros'll besides get over some sponge alternatives that tin assist you reduce household waste.

Microwaving a sponge can impale bacteria.

A 2007 study from the Agricultural Research Service, part of the U.S. Department of Agriculture, found that microwaving a sponge killed 99.9 percentage of germs — slightly more constructive than throwing a sponge in the dishwasher.

That's because radio-frequency waves in a microwave cause thermal (estrus) and nonthermal (not-heat) effects, causing the water molecules within a jail cell to vibrate. The friction associated with this vibration causes increasing levels of heat, which kills the leaner.

Recent research has too supported this method.

A 2020 report asked xx participants to employ kitchen sponges as normal for 4 weeks. Ten of these participants were instructed to clean their sponges two to three times weekly in a microwave for at least 1 minute at a fourth dimension at the highest wattage.

The results showed that sponges microwaves for at least one minute 2-3 times each week had significantly fewer bacteria than the untreated sponges.

Results tin vary depending on the heating setting of your microwave. Certain microwaves may require more time to sufficiently kill leaner, or may not accept wattage high enough to completely eliminate bacteria.

Your sponge can comprise several billion bacterial cells in every square cubic centimeter of sponge fabric — that's co-ordinate to a 2017 study in Scientific Reports.

And it's likewise probable that a lot of bacteria found on household surfaces and appliances were introduced at that place by a sponge because many people leave their kitchen sponges wet. Sponges accumulate clay and bacteria quickly, and leftover food particles are some other factor that tin can also breed colonies of bacteria.

Hundreds of bacteria tin alive on a sponge, including:

  • Eastward. Coli may give yous an upset stomach and/or diarrhea.
  • Enterobacter cloacae tin can cause pare and intestinal infections, among other illnesses.
  • Klebsiella oxytoca can crusade vaginal infections, like a UTI.
  • Mycobacterium avium can cause pulmonary-related diseases in people with weakened immune systems
  • Staphylococcus aureus (Staph) can crusade a staph infection that results in fever, swelling, and irritated skin.
  • Salmonella can cause food poisoning.

How long you utilise a sponge depends on apply.

If you're using information technology every twenty-four hour period, consider replacing your sponge at to the lowest degree one time a week. If you utilize a sponge to make clean raw food spills, sterilize or replace it right away.

Simply if you lot sterilize your sponge regularly, y'all tin likely supervene upon it every 2 weeks without any significant health risks.

Additionally, tap into sensory cues. Consider replacing your sponge if information technology:

  • looks dirty
  • feels slimy
  • has a foul or aberrant aroma

At that place are other constructive cleaning methods for both your sponge and other household items that don't require you to use your microwave.

Use a dishwasher

A 2020 study in the International Journal of Food Microbiologyplant that dishwashing is a highly effective method for reducing bacteria, specially salmonella.

Alex Varela, possessor of Texas-based house cleaning service Dallas Maids, suggests that yous should make clean your sponges by "placing them in the dishwasher and running the heated dry out bicycle."

For all-time results, put the sponge in the top rack of a dishwasher and wash information technology with the sanitization bike.

Use bleach

Bleach is a powerful cleaning agent that kills bacteria and viruses.

To clean your sponges:

  1. Get a small-scale tub and fill it with bleach. The Centers for Disease Command and Prevention (CDC) recommend 1 cup (240 mL) of bleach for every i gallon of water.
  2. Place the sponge into the solution to soak for v minutes.

Apply baking soda and vinegar

Baking soda gets rid of odors and distilled white vinegar volition handle bacteria:

  1. Wring your sponge well and get out it to dry overnight.
  2. Sprinkle the softer side of the sponge with a lot of baking soda. If at that place are two soft sides, yous just need to pick one.
  3. Grab a pocket-sized container and fill it with vinegar and then that the sponge is nearly covered but not fully immersed.
  4. Carefully identify the sponge in the container and keep the baking soda office on top of the bath of vinegar.

Use vinegar

Instead of baking soda and vinegar, it's also possible to just use vinegar:

  1. Take a dish large plenty to hold the sponge and make full it with vinegar.
  2. Soak the sponge in the dish for v minutes.
  3. Wring out the vinegar.
  4. Thoroughly rinse the kitchen sponge in warm water.
  5. Let the sponge dry out fully.

Here are some options for a sponge culling that may be more than sanitary or longer-lasting:

  • Silicone sponge. These are antibacterial and don't produce microplastics. Silicone sponges are easier to clean because they have flat, sealed surfaces. They're also eco-friendly since yous don't have to replace them as often.
  • Handheld dish castor. This tool keeps your hands cleaner and it can be stored upright. This tin can help it dry faster. Look for brushes whose handles are made from natural materials similar finished wood or other compostable products.
  • Loofah. A natural loofah is fabricated from a gourd in the cucumber family and can be a more sustainable cleaning tool than sponges or other kitchen cleaning tools made with plastic or other manufactured materials.
  • Body of water sponges. These eco-friendly cleaning sponges are naturally found in the ocean and aren't very abrasive.

Putting a sponge in the microwave is a proven fashion to kill bacteria and germs, reducing waste by allowing your sponge to last longer.

Just be sure to wet the sponge beforehand to avoid any safety hazards and toss any sponges that develop a bad odor or slimy texture.

Consider other, more sustainable cleaning alternatives like silicone or body of water sponges to reduce even more waste product.
