Using these pillow covers is a breeze. Just unzip the cover and insert your pillow. They're great for sprucing up your living room couch, outdoor patio furniture, or even your bedroom. When it comes to maintenance, since they're water - resistant and mold/mildew resistant, you can simply wipe them clean with a damp cloth for regular cleaning. If they get really dirty, you can gently machine - wash them in cold water on a delicate cycle. Avoid using harsh chemicals or bleach as it might damage the polyester material. And remember, these pillow covers are for non - commercial use only.
