Kodak D76 and dish soap

[Sebastian_F]

I cleaned a pot with dish soap to heat up some distilled water in order to mix it with Kodak D76 powder.
I'm worried that I may not have rinsed the pot well enough and that there may have been traces of dish soap left in there that got into my D76 solution.
I think this is the case because I saw some soap bubbles when I was pouring the water in.
Do you think this contamination is an issue? Will it affect my negatives? Should I throw it out?
It definitely wasn't much dish soap but I'm afraid that some trace amounts were left.

Thanks!

I wouldn't risk it.
FWIW, use the pot or a kettle or a microwave oven to heat up water for a hot water bath.
Then put your distilled water into your mixing container, and then put the mixing container into the hot water bath, in order to heat the distilled water indirectly.

It says in the instructions on the E-6 and C-41 kits that a drop of dish soap can be enough to ruin the developers. I guess it all depends on how much was left over.

Not really.

Any traces of soap will act as a surfactant. This in itself is not necessarily a bad thing. Color developers include surfactants on purpose, so do some types of film, as it promotes even wetting.

It'll be fine.

You can do a clip test to see if your developer is working. Take a piece of exposed film leader and drop it in a small cup/tank/whatever with developer, and see if it turns black/opaque in a few minutes. If it does then the developer is active, and if not, then not.

There are so many questions about "is my developer / fixer still good" or "I developed / fixed with old solution and it's messed up" that could be addressed by testing the solution with a scrap of film.

Color developer is different from B&W developer (dye couplers etc) and may be subject to more stringent contamination requirements.

Just try it and see.

I've not been processing films for very long (compared to a very few others here), but I have NEVER seen that comment anywhere, Oh and I cut my teeth on Pavelle printing/processing, the awful Ferrania reversal process, E3 . . . . . . . . . and many years of E6 & C41, just watch for foaming, whuch is unlikely

Reality is any liquid soap, a surfactant, is not a contaminant that will inhibit development.

Thanks I will try this

Your perfectionism is ruining your process. Don't ever use soap and don't used distilled water to mix D76. Just use tap water.

Film developers are a foamy lot even without added dish soap!

Which chemicals, other than surfactants, cause bubbles in film developers? Or which developers have the fewest bubbles?

When I develop film in daylight tanks as one-shots, I always dump them into a large bucket. In the past, I always noticed lots of bubbles there, when I was using developers with sodium sulfite such as d23, d76, etc. I recently changed to a sulfite free developer, Gainers Original MC developer...

I doubt also that it will cause problems, in fact if you have very hard water, it may be a blessing.

I wonder if the term "clean developer" which I have heard used to describe some developers, stems from just such an action that the OP thinks he may have made here?

I'm not worried too much about the soap.
I'm concerned about what else might be in there, to give you soft hands and a kitchen that smells like a forest glen in spring .
