The best solution and have found (and done many times) is liquid laundry soap and a good wide tire scrub brush. The generic laundry soap seems to work the best! You can get a cheap bottle at your local $$ store. The wide tire brush is stiff enough to clean, but soft enough to not rip the liner. I put the soap into a wide angle spray bottle and sprayed about a 1 ft section at a time. Then scrub and rinse as you go. It is time consuming, but it will work to remove the stains, new algae, and restore the liner material. Most chemicals actually slowly deteriorate the liner! Also works great on the outside of the vinyl and soft side pools.
