If you want to prevent the cutting board from cracking, you should coat it with cooking oil immediately after buying a new cutting board. The practice is to apply cooking oil on the upper and lower sides and around the cutting board, and then apply it three or four times after absorbing the oil. It is easy to crack around the chopping block, so you can brush it several times repeatedly until the oil is dry. After this treatment, the cutting board is not easy to crack. Because oil is highly permeable and nonvolatile, it can moisten wood for a long time and prevent the chopping board from bursting. Oiling also has anti-corrosion function, so the cutting board is durable. There is another method that I often use, that is, after I buy a wooden chopping board, I brew it with strong brine, depending on the thickness of the time. If it's a pier, it's almost a week. The advantage of this method is no pollution and can be sterilized. The disadvantage is that it needs a large basin and takes a long time. It is said that people in rural areas can soak in wells or pools, and the effect is good.
In addition, the daily protection of chopping boards is as follows: 1. First, blanch with boiling water to wash off this layer of wax, which can prevent wood from cracking. 2. After washing, be sure to soak in strong salt water for one day. Strong brine means boiling water and adding salt while it is hot until it no longer dissolves. The purpose of soaking in concentrated salt water for one day is to make the wood surface salty and absorb water, which can prevent the wood from drying and cracking. 3. After soaking, heat a pot of oil, cool it to about 70 degrees, smear the surface of the cutting board, let it stand for a while, smear it again, and smear it several times. When the oil is almost absorbed, dry the oil with paper and the cutting board can be used. In addition, if the cutting board is not used for a long time, it should also be oiled and kept flat.
