Hello, New pool owner here who made the mistake of cleaning my dirt crusted automatic pool cover with SOS pads (the pool cover is 3 years old). At the time, I could not budge the built up red dirt of Southern Utah. Yes, I feel foolish now!
After using the SOS pads, the light gray cover was spotless for days. Then after a heavy rain, brown and dark purple line and circular stains appeared. Next, I cleaned the pool cover with diluted 'Bar Keepers Friend.' This time the pool cover came out fairly clean, but days later similar stains reappeared.
I have no idea what I am dealing with but may be rust or a reaction due to the SOS pads? If rust, I read Clorox was not recommended. How about diluted CLR?
Any advice on what to use to clean next is greatly appreciated!
