What Are Some Effective Ways To Disinfecting Kitchen Sponges?- Yancheng Oukai Sponge Products Co., Ltd.

There are basically three ways we can think of to reliably disinfect kitchen sponges:

Immersion in a suitable liquid disinfectant solution for suitable amounts of time. ‘Suitable time span’ will depend on the product used and a slew of other factors. Some candidates:

Chlorine based products (aka bleach)

Alcohol based products (usually relying on ethanol or isopropyl as the active ingredient)

Hydrogen Peroxide solutions

All sorts of commercially made products based on other microbicides.

Exposure to heat above a certain temperature for a certain time. Again, times and temperatures vary. Some ways to achieve that:

Immersion in boiling water for a couple of minutes

Immersion in hot-but-not-boiling water (above 85°C) for a quarter hour or so Exposure to saturated/superheated steam for certain lengths of time. Pressure cookers, commercial food steamers, medical autoclaves come to mind as workable devices for that.

Exposure to dry heat. Ovens etc. You'd probably need temperatures that will degrade the sponges’ material for reliable results, though.

Exposure to radiation. Alpha, Beta or Gamma rays are probably out of the question, high intensity X-rays don't strike me as a viable alternative, either. Microwaves? Maybe. I'd hate to have to figure out a reliable method for using a consumer-grade microwave oven for the purpose, though. Ultraviolet works great for surface disinfection, but I wouldn't bet fuck all on kitchen sponges being UV permeable.

Or a mix of the above. A 95°C washing cycle with somewhat aggressive laundry detergent will do the trick, as may a trip through the dishwasher, for example.

In practical terms? The things are disposable items. Use them till they're grubby, store ’em on a well-ventilated rack during that time and throw them out when they start being yucky.

Also, unless your procedure for washing dishes is seriously messed up, they don't need to be sterile. They're used to scrub off solid-ish residue, the final rinse under hot water should be what gets rid of harmful bacteria on your dishes.

If you're paranoid about germs (which you really shouldn't be), sterilize your dishes after washing up, not your dishwashing sponges.
