Our cushion covers are treated with a water repellant coating. Spilled liquids can be easily wiped off.
We recommend removing and storing the cushions in a dry place when not in use. By doing so you can preserve the coating and extend the life span of your cushion covers. The covers are machine washable on cold.
Exposure to sun and rain will break down the coating over time. The same is true for washing the cushion covers. Water repellent coating can be re-applied. There is a variety of products out there, often sold by boating stores or marines, which can be sprayed onto the covers.
