Long story short. Bought a house on short sale that had the pool.clearly the pool was neglected. We took the plywood cover off this weekend and this is what we saw (see pics). We drained the water, I'm aware of the Sayers of draining a pool with a vinyl liner but I'm just curious on how you guys would attempt to clean this? Im talking aboit the black line on the wall not the leaves on the bottom. It is an 18x36pool so iI'd prefer to save the liner if I could. Oh and fyi....pressure washing the liner did nothing. Worked great on the stairs but wouldn't help the liner at all.
