Cleaning is required less frequently in a dry environment than in a humid one with heavy foliage. This practice will help prevent dirt from becoming deeply imbedded in the fabric and eliminate the need for more frequent vigorous cleanings. In most environments, a thorough cleaning will be needed every two to three years. Water should be cold to lukewarm. Never more than 100 degrees.
Air dry only.
Use a soft bristle brush to clean. Allow soap to soak in. One gallon of water. Clean with soft bristle brush. Allow mixture to soak for up to 20 minutes.
