Sodium hydroxide usually is "caustic soda." "Lye" can be potassium hydroxide. The washing soda you buy in the store is sodium carbonate decahydrate (Na2CO3.10H2O, molar mass 286) while the Kodak recipe is made with anhydrous sodium carbonate (Na2CO3 molar mass 106), so you need 2.7 times as much washing soda as anhydrous sodium carbonate to get the same amount of Na2CO3.
Hey that’s interesting! I wonder how much difference we see between the Kodak version and washing soda… bc we obviously can get viable negatives with 100 mg of washing soda… so is the idea that you could use nearly 3 times less of the Kodak chemical over washing soda? And if that’s the case maybe it’s an argument for cost but then again the Kodak cost would arguably need to be cheaper by a good bit and that still wouldn’t equate to how easily it is to acquire washing soda… tell me if I’m on base with any of this compared to what you were mentioning!
Really they’re doing 2 things… removing before the roll is shot, whereas this would be removed after the roll is shot… and 2. They’re doing it on large scale to the public
They're probably not even doing that these days, pretty sure they get vision without the remjet straight from Kodak. They just mark the rebate info on it, cut it and pack it.

Great video!
Kodak also give a second recipe for remjet removal. Without Borax. Works great for me.
That’s pretty sweet!
Wait so this is all cinestill does lmao people always made it seem like they were really doing something novel
