Echo Eliminator panels have a special facing that is more durable than most acoustical products. Accumulation of dust and dirt are best removed from Echo Eliminator with a soft brush attachment on a vacuum cleaner. Use vacuum attachments with a least 1" soft bristles to avoid damage to panel. Echo Eliminator panels may also be brushed off with a soft-bristle brush or blown gently with compressed air. Dirt may also be removed with a dry sponge; a damp, white cloth; or similar. Heavy soiling and stains may require a product like Resolve® or Spot Shot® carpet cleaners, which should be used as directed. Test first on a small (or hidden, if possible) area of the panel. Allow test area to dry completely and look for any discoloration. Heavily damaged panels should be replaced
