Using these pillow covers is a breeze! Just zip them open and insert your pillows. They're perfect for sprucing up your indoor sofa or outdoor chairs. When it comes to maintenance, since they're water - resistant, a quick wipe with a damp cloth should do the trick for minor stains. For more stubborn dirt, you can gently hand - wash them in cold water with mild detergent. Make sure to air - dry them thoroughly. Keep in mind, these pillow covers are not for commercial use. Also, as they're UV - resistant, they can handle sunlight well, but it's still a good idea to store them indoors during extreme weather conditions to extend their lifespan.
