Some mats can be machine washed, but usually handwashing is better suitable for these mats. You can use a mild detergent mixed with water and scrub the mat gently. For scrubbing, you can use a soft brush or a damp cloth.
If you want to machine wash your mat, check the manufacturer’s instructions beforehand. You can use cold water, and a gentle cycle to wash the mat.
After washing the mat, it is essential that you dry them properly to prevent the growth of bacteria caused by moisture. Dry the mat in areas that have lots of ventilation but not direct sunlight. Exposure to direct sunlight and UV rays can damage the mat and fade its color.
