How to use: fill the bag half-full with any clothing that contains synthetic materials (polyester, polyamide, nylon, spandex, acrylic, elastane, etc). This includes fleece jackets, active wear, outdoor gear, socks and underwear, and so on. Once the washing is done, the fibres will collect in the bag. Use your finger to sweep out the lint and throw the lint away to keep it out of the water supply.
