There are a few things you can do to clean a pool that has been sitting for a while. First, make sure all of the water is drained and emptied. This will help to remove any dirt, debris, and other contaminants that may have been left in the pool. Next, use a plunger to suction onto the bottom of the pool and pull until all of the water has been removed. Finally, use a vacuum cleaner to clean any areas that have not been cleaned before.
