Iron oxide

[zita-green]

Is there a way to remove iron oxide deposit from the inside of an old glass bottle; it's one of those with a glass marble inside.

Oxalyic acid is used for iron based stains. That is why it is far better on bloodstains than ordinary bleach. Haemoglobin has high iron content.
