Iron staining remove

[Vicen Carrio <v.carrio@xxxxxxxxx>]

Hi,

I would like some help. I do have some plants from St. Clair Pit (Pennsylvania)
with iron staining which have to be removed.

I have used in the past sodium dithionite to remove iron staining from minerals,
but been plants I don't think a 24 hours bath will be suitable for them.

Any suggestion?

Vicen
