Remove the cover and scrub both sides of it with brooms and soap and water(I think we used a mix of dish soap and a little bleach). we lived on a quiet street and could wash and let it dry in the middle of the street. Reconnect the filter, you might need to get new sand depending on how old it is. Fill the pool to the proper level. Take a clean jar of the water to the local pool supply place for testing. Give the pool a good vacuuming, add the chemicals as needed. Should at least get ya started. Enjoy.
