It is usually recommended to dry clean pvc coated fabric, but it can be washed with cold or warm water and mild detergent. Remember not to machine wash PVC coated fabrics.
Use a spray bottle or non-abrasive tool to apply the cleaning solution. If this is not enough to clean the PVC-coated fabric, you can gently clean it with a soft brush. https://www.zd-fabric.com/product/pvc-pu-fabric/
