I was underwater today. and a stain appeared on the white light housing. I cleaned the light with Vitamin C and the stains appear to be gone. Although. the screws seems to be rusting, not on the outside, but where the screw driver tip grabs the screw.
Is this normal? Could the chlorine be rusting these screws? All the other screws on the returns (6 of them) are all in tact, without any rust.
There probably is not a warranty from the pool company. As these are under water, what would be my next step? Call the manufacturer? Or can these screws be removed and replaced under water, or do we have to drain the water and fix? Not sure.
