can this be used to remove rust stain from a fiberglass swimming pool?

Works best on metal when it’s Hot out. Try CLR. Going to be tough if the stain was there long and it made it into the fiberglass. Good luck

Is this citrisurf 77 or citrisurf 77 plus? the picture shows citrisurf 77 plus but the title says citrisurf 77.

It is Citrisurf 77 Plus. I will personally address this title error now. Thank you!

How do I safely dispose of this?

Great question! Small quantities can be poured down the drain, best with some running water to dilute. Industrial disposal of large quantities would involve neutralizing the acid first. The product does not qualify as hazmat.

can this be used on brass bed?

I'm sorry, but this product is ideal for Stainless Steel, and we haven't tested it on brass.
