How often should you change kitchen sponge? Scientist settles debate

"If for something likely to be germ ridden such as dirty vegetable or raw meat or fish, then I dispose of these after a single use as it is not easy to clean all microbes off a kitchen sponge. For everyday usage, I throw my sponge away after a single day - and during this day, the sponge will get multiple antibacterial detergent treatments."

"If you're using it daily? You should definitely replace it weekly. At least. And keep it clean and dry when it's not in use,"

Kitchen sponges harbor high bacterial loads and should be replaced daily for routine use. Sponges used on raw meat, fish, or dirty vegetables should be discarded after a single use because microbes are difficult to remove. An experiment tested sponges used from one day to five months, with occasional disinfection, and microbial analysis showed substantial bacterial numbers. Many people report weekly replacement or avoid sponges altogether due to germ concerns. Daily use often involves multiple antibacterial detergent treatments, yet contamination still accumulates, making frequent disposal the safest hygiene practice.
