Has anyone tried using other sources of surfactants for film drying? I know dish detergent is frowned on, but they sell industrial wetting agents at gardening centres for getting water into high-silicate soils. Anyone tried that?
For those of us without access to a lifetime supply of Photoflo-2100, it might become an interesting question soon. My previous bottle of Photoflo-200 was $3.99 (2009) and I've got 25% left. Concerned at Kodak going bust, I bought a new bottle last month: $12.99. I don't reckon I'll be able to buy any more at any price in Australia as the shops say it's discontinued and I got the last bottle from my local store.
