WASHING & HANDLING INSTRUCTIONS: All Spero products use silver fabric which acts as a faraday cage. The silver fabric must be delicately handled if washed. Wash by hand with distilled water and SPERO Silver Fabric Detergent, or a gentle natural soap. Tap water or well water will ruin this fabric as chemicals in the water such as chlorine, sulfur and fluoride are corrosive to silver. Hang dry.
