The polyvinyl-coated cotton fabric is generally water repellent and should repel most soil. Should the fabric become soiled, cleaning should be done with a soft cotton cloth or soft toothbrush slightly dampened with distilled water (sodium-free seltzer water may be substituted) and a mild bar soap, applied in a circular motion. Repeat with distilled water only to ensure no residual soap remains. The material should then be allowed to dry completely. Strap drop length: 8.25". H 9.5" x W 6" x L 11.5" 12 oz
