These red and white throw pillow covers are super easy to use. Just unzip the cover and insert your pillow insert. You can use them indoors on your couch, bed, or outdoor patio furniture to add a pop of color and comfort. When it comes to cleaning, you can spot - clean them with a mild detergent and a soft cloth. If they get really dirty, you can machine - wash them on a gentle cycle with cold water and then air - dry. Avoid using bleach or harsh chemicals as it may damage the UV - protected polyester material. Since they are UV and water - resistant, they can withstand normal outdoor conditions, but it's a good idea to bring them inside during extreme weather like heavy storms. There's no need to assemble these pillow covers, so you can start using them right away.
