Soap is made from animal fat and hydroxide. To make it pH neutral you have to add an acid. The mixture decomposes over time to release sulphur and other nasties detrimental to your negative. In addition, soap reacts with the dissolved salts in tap water to form an insoluble scum which can end up on your neg.ĭetergents are manufactured from oil and are complex long chain molecules which again can break down over time. In addition, detergents contain other compounds designed to do different things - remember that they are designed for washing greasy dishes - which themselves decompose. You need the following dependencies to build Photoflow: gettext, glib-2.x, libxml-2.0, pkg-config, swig, gtk-doc-tools, automake, gobject-introspection, gnu make, cmake, libtiff, libjpeg, libfftw3, exiv2, lensfun and gtkmm-2.x or gtkmm-3.x. In both cases they have to be used at quite high concentrations in order to work effectively and this results in a sticky coating of soap/detergent remaining on the neg. People who use soap or detergent and claim it works fine usually use it in such incredibly low concentrations that it does not actually do anything.

Wetting agent is normally ethylene glycol (it's used in car antifreeze). I use it as part of a formula for cleaning vinyl LP's. Ilford Wash Aid is a substitute for Kodak Hypo Clearing Agent. This compound has a relatively small molecular size, is chemically inert and is pH neutral. It tends to leave the neg along with the water - any residue is undetectable. The bottom line is - use the proper stuff. Get complete app visibility for everything from backend APIs to frontend user devices with New Relic Application Performance Monitoring. of PermaWashing after a water rinse, and also saw me switching over from Ilford Ilfotol wetting agent (couldnt find it anymore) to Kodak PhotoFlow.
