Sponge dishwashing generally saves detergent and has a very strong adsorption capacity for hidden things, so it is a very good dishwashing tool.
Sponge is a porous material with good water absorption and can be used for cleaning articles. When selecting a sponge, its tactile sensation and elasticity are the primary judging factors. It should feel soft and malleable.
In addition, one of the most practical identification methods is to fold the sponge in half and rub it against each other. If the sponge crumbs fall off without rubbing a few times, it should be eliminated.

Formaldehyde is highly toxic and has long been identified as carcinogenic and teratogenic by the World Health Organization. Even long-term exposure to low-dose formaldehyde can cause chronic respiratory diseases, menstrual disorders, pregnancy syndrome, and memory and intelligence decline of adolescents. So how can we safely use the clean sponge with excessive formaldehyde?
First of all, this kind of cleaning sponge will volatilize formaldehyde when placed in the room. In this regard, Sun Lili, inspector of the League of Nations, suggested: "Formaldehyde has a characteristic that it is extremely soluble in water. The newly bought cleaning sponge should be cleaned several times and put in a ventilated place for a while before use. "
After washing dishes with such a cleaning sponge, how can we avoid water containing formaldehyde remaining on the tableware? Sun Lili said: "After washing the pot and bowl with a clean sponge, rinse the pot and bowl with clear water again, and then control the water stains in the pot and bowl."
