But doesn't Palmolive soften your hands while you do your film?
I'd heard the dish-soap thing before from someone working in a photo store. He told me only use it in a "pinch" (if you really really have to and can't get the correct stuff), and that with proper technique surfactant probably isn't even needed.
not so sure i would recommend that at all
(there was a url link here which no longer exists)

it leaves soap scum ..
jnanian, you are missing the point that I have been making. If I were to recommend Clorox bleach replace the bleach for C-41 processing, would you have worked so hard to get around the point?
nope i would agree with you 100% ..
but you used photoflo ( which i agreed with you 100% ) and
borax ( which can be used successfully ) ..
my point is that there are things that can be used with no ill affect
if they are not photo grade or pharma grade or just sold off the shelf
at abc-mart.
but i do agree with you .. there are a lot of foolish people who do foolish things.
The pH produced by sodium tetraborate (borax) and sodium metaborate (Kodalk) are quite different and one cannot be substituted for the other. Borax is a mild alkali while sodium metaborate is almost a alkaline as sodium carbonate. If the FDC says that they are interchangeable then this is another error in a poorly edited book. Borate chemistry is rather complex and the naming can be quite confusing.
Years ago I contacted US Borax about the purity of Twenty Mule Team borax. It is more than pure enough for photo purposes. The principle impurity is a very small amount of sodium chloride.
thanks gerald
i was going by what is quoted here:
http://www.largeformatphotography.info/forum/showthread.php?57351-Borax-Kodalk
that in some instances it can be a useful substitute.
i don't have any borax, or kodalk, only metabrate ..
so i really can't say if it works or is absolutely foolhardy.
i haven't made divided d-23 yet ( which is what i got the metaborate for in the first place )
so i can't even make a comparison between the original recipe and the one Anchell & Troop's Film Developing Cookbook
suggest can be done instead with borax ...
but i agree with a lot of what you ( and steve ) have said
that people do foolish things to save a few cents, and often times in the end it is a waste of time and money and energy.
