new stains showed up suddenly after a week or two of rain during which I didn’t stay up on brushing, etc. It’s old plaster that has a lot of other widespread brown stains, but I was hoping to avoid any further staining…
The new stains are these tiny brown stains. Like flecks or brown. See pics; this is only about the dark brown, very small well defined stains—not the discoloration you see around them. Only the dark flecks are new.
. I have shocked pool, scrubbed the stains, applied muriatic acid directly to them, applied ascorbic acid directly to them. Nothing changed the stains one bit. I’m stumped.
See pics. Any ideas?
