Any ideas what this blemish inside could be?
Rust colored stain in basin. I have scrubbed with a bottle brush and scraped with a knife but it won't dissolve.
I have mostly only really drank water out of it.
It was dropped and lightly dented but it's about 1/4 of the way around the bottle from the stain.
What is this stain? Should I continue to use it?
