I've just noticed that I've managed to stain the vinyl liner in the pool in my new rented house.
99% sure I've done it with two different chemicals, once with cyanuric acid and once with Borax.
The stains look like light brown/tan patches about an inch to 3 inches across, both the stains look similar even they were caused by different chemicals.
The pool liner is light blue.
Is there a way to get rid of them?
Thanks in advance,
