I've managed to soak a demijohn in bleach solution for too long (again!) and have got a scaly deposit on its inside surfaces. Last time I used some citric acid to remove it and it worked well, but I've run out.
Would I be right in thinking that a starsan solution is similarly acidic and may be able to remove it too, or have I completely invented that?
Cheers,
Kev
Starsan vs Citric acid on scale?
