Is it possible my Polaris 480 is staining my plaster? I have several spots around the pool bottom that looks like something sat there and made a round spot.
You'd think the Polaris wouldn't have anything that could rust/stain.. but I had it out last week to change an o-ring and let it sit on my decking for a few days and there was a spot right under where the polaris was that stained my deck brown/red (like a rusty screw/nut dribbling rust water out?)...?
If that's the case how can I fix this.. both the polaris and the stains?
