To remove any dirt or solid items, wait until it is dry and use a soft bristled brush. A microfibre cloth and straight water can also be used to anything stubborn. Much like any heavy duty canvas tent, to clean your TreePod you need to use a canvas cleaner. After every clean you will need to reproof the fabric. Such cleaners (like Nixwax, Graingers or Fenwicks) can be purchased from most outdoor stores, such as Hunting & Fishing, Macpac, Kathmandu or from us. DO NOT use your everyday household cleaners or detergents to clean your TreePod.
