How to deal with moldy cutting board: you can use stainless steel cleaning wire or sandpaper to rub the place with moldy spots, and then rinse with water and scald with boiling water, but this method can not completely remove the moldy spots. You can also dip the vegetable board in rice washing water, scrub it with salt or alkali, pour some vinegar on the vegetable board after washing, dry it in the sun, and then wash it with clean water.
The chopping board is an excellent place for bacteria to hide. The uneven knife marks on the board are full of nutrients and dark and humid, which is just suitable for the survival and reproduction of bacteria. Someone observed with a microscope and found that there were 2 million Staphylococcus, tens of thousands of Escherichia coli and other bacteria on the cutting board per square centimeter.
