If it dissolves in water, then what does a lengthy presoak in water do?

How long a presoak, and why would you do that?

Does DHMO dissolve in water?

I hope you're joking....
DHMO is DiHydrogen MonOxide, or H20, AKA water. All the statements on the linked site are correct, just blown out of context so it appears to be a nasty toxin

You mean it's just water??? Yes, just joking. I was wondering how long it was going to take before someone asked me about it.

to allow the developer to work more efficiently and get rid of the purple/blue dye, I generally pre-soak 5 minutes in distilled water with no agitation. Until someone tells me why I shouldn't, (not just that I don't need to), I will continue, because it works. No more purple stain at the end of processing. But that's another topic.

You had me worried for a minute there, Jim

I stated that in an earlier post along with information on DMSO as well. I'm surprised that everyone missed it.

Well, there are times...

I got it when you mentioned it. I just didn't want to reveal how slow I was! It was, frankly, a bit embarrassing. That DHMO website was insidious, sly, and wonderful.

What I always wanted to see NASA (0r any other bigwig science outfit) come up with was freeze-dried water. Think of the people around the globe who could be helped by this! Holy cow, just add water and you've ...water!

What? You don't have some? It is part of everyone's required emergency kit. I've got an almost unlimited supply right now.

I'm waiting for true Black Light, not that phony ultraviolet stuff. When you shine it on something, it should make it darker.

Ever hear of dehydrated beer? It was old Frothingslosh. A whale of an ale for a pale stale male!

There was talk of freeze-drying booze, but I don't know what became of it. There is freeze-dried ice cream. Pretty bad stuff, you DON'T add water, just eat the dry powder.

Yep...long term soaking of gelatine emulsions in water can cause them to dissolve right off the base.

So very true, I was cleaning some family negs from around 1915 and others from the 50s. The Kodak safety film from the 50s would never clear up, so I did the same, with the same results. I was about 17, and it's never happened again.
