Thanks for the feedback, guys. I tried the old-fashioned method of bleach and water. I purchased a couple of the scot-brite scouring sponges and a scrubbing brush at the local Wal-Mart and must say the results were quite dramatic. The steps and jacuzzi seats no longer have dirt marking the water line and the diving board looks like it was replaced, because it is bright white, the color it was supposed to be Thanks again for the feedback. Incidentally, the entire cleaning took less than 30 minutes, so I am quite impressed what great work a little brush does!
