Hi all I live in South Florid and I just drained my very very green pool. It has not been running for 2 month as I had to have the tenant served with an eviction notice. I have one question on what is the best way to clean the diamond brite surface. It is 10 years old and it was cleaned with a pressure washer about 5 year ago by me. But some of the finish came off with the pressure washing, so what should I do?
