I just had my entire pool chipped out and refinished with stone scales mini pebble in May of 2021. I haven’t had any issues at all until recently. Earlier this week my wife said she noticed a small rust stained looking area near our steps….she tried brushing it and I didn’t think much of it. Today we noticed multiple areas around the steps that are now stained. I have no idea what it’s from and brushing it didn’t make a difference. The pool is maintained professionally weekly as well. What options do I have to try and remove these stains? Here is a pic of the area though it’s more obvious in person…
