There are a few things you can do to clean a pool cover:

  1. Remove all of the dirt and debris that has built up on the cover over time. This will help to remove any bacteria or other contaminants that may have been left behind.
  2. Use a plunger to push and pull the dirt and debris out of the pool cover. Be careful not to damage the cover in doing so.
  3. Rinse the cover with water and then dry it off using a towel or air-drying device.
