I'm not sure. Mine has gotten dirty and moldy from being rolled up in the same position for so long. I've been able to knock some of that dirt off but, it's hard to reach out there far enough to physically remove the crud. It would be great if there was a product that I could hook to the end of my garden hose that would spray on cleaner from several feet away. But, I haven't found one yet that looks like it would work.
