Put it into the washing machine and wash it in soft washing mode 10 minute. Just use detergent or soap powder as detergent, and don't use washing powder, because it is not easy to clean, and don't soak for too long, because bamboo chips are easy to deform when they contact water for too long. Finally, when cleaning, drop a little toilet water in the water, which tastes better, feels cool when sleeping, and can repel mosquitoes. It is more important to dry, spread it out in a large area and pay attention to turning it. Be careful not to expose it to the sun, otherwise the bamboo pieces will be deformed. Make sure it is completely dry before you put it away. Otherwise, it will be moldy! You want to make a mat yourself. I wish you success!
