Hi,
The stone feature around my pool has white build up at the water line (Probably due to hight pH, see my previous post where I mentioned high pH). Also there are black & green stains on the top side of stones. I am adding pictures. When I bought the house 6 months ago the stones were super clean and looked beautiful.
So how do I
1. Clean the white stains and black/green buildup up?
2. And how do I prevent it from happening again? Is there a paint or something that makes them look nice and also prevents the build up in future?
I tried using orange oil on a small area with green/black buildup and scrubbing with metal brush, it seemed to help but I was worried if it will damage the stones and the green residue dripping in water.
