wooden mats should be properly maintained every day. They can often be boiled with hot water or sun dried and sterilized. However, they should not be exposed to sunlight to prevent the wooden mats from cracking due to the sun's excessive sunlight.
Keep salt on bamboo mats once a week.
White vinegar can also be sprayed on the wooden mat, put it in for half an hour and then washed. It can not only sterilize but also deodorize.
If the wooden mats are seriously mouldy, the scrubbing method is not very useful. You can plan to use the plane to mold the moldy layer or change the wooden mat directly.
