Re: Removing Cyanotype Solution from a Stouffer Wedge

Sistan. No.
Sodium Bi Carb. Nothing.
Borax. Nope.
Ammonia. No.
CLR. (Rust remover). Not really. Something fizzed but it may have been

Bleach. Yes, but also bleached the Stouffer wedge to death. RIP.

Looking for his credit card...(actually I have a spare wedge).
