The protector is really easy to take off to wash. Find the zipper and unzip this all the way round. The top section of the protector will completely unzip from the bottom. This mean it is really easy to take it off and wash it. Once the top layer has been washed and is fully dry, you can easily zip this back on to the bottom layer. This means you don't have to struggle to take the bottom layer off every time you need to wash it. If you wish to wash the bottom layer as well, unzip the top layer fully off, then you can carefully pull the bottom layer out from underneath your mattress.
