ILFORD WASHAID is a hypo-eliminator formulated to aid the efficient removal of the thiosulphate by-products of fixation by ion exchange. It is particularly useful. Ilford states that their Washaid can be used with prints and film. Has anyone used it with film? What exactly does it do? The information on their. Hello, I recently purchased a bottle of Ilford Wash Aid to act as a hyper cleaning agent after using the fixer. I used to use Kodak Hyper.

Aug 4, 3. Developing films on higher temperatures will made them very sensitive for scratches and damage.
Futher your wash time will be longer when using a lower wash temperature, one of the reasons a film wash between degrees C after a 20 degrees C processing is in fact recommended. This you can test with a KI Potassium Iodide solution.
I think I’m getting it sorted out in my washadi now!
Good to know it’s not a big issue. It’s more difficult to control the temperature at 24degC in the UK, particularly in the colder months, but I always use a water bath and allow the bottles and tank to stand in there for a while before processing begins. I live in an area washajd soft water so I had to dilute extremely, your water might allow less extreme dilutions.
I don’t use a hardening fixer and it’s probably the most important bit. Lex has described why you do not want to agitate the surfactant type wash aids.
I use 20 degC for developing times up to awshaid 15 minutes and 24 degC for those that would be longer, e. It is particularly useful if a hardening fixer has been used. The effective result depends on the D. Oh and the most important thing about learning to develop film is to stick with one film and one developer until you feel you have mastered it.
All you need to know about developing and printing is there, plus ilforx are fact sheets for each product. Due to the fact used fixer is wasuaid heavy metalls, you have to get rid of it in the chemical disposal. Anything that reduces the surface tension of water will increase foaming when the water is agitated. I’ve never formally tested this fact, but I’ve never had any issues with my film either.
Suitable for slow and medium speed ilrord. I used to use Kodak Hyper cleaning agent, but changed for the sake of convenience – I didn’t have enough storage bottles at the time as the Kodak agent was originally in powder form to make the stock solution.
Hope you find a combo you like! There is always a minimum amount of concentrate you need to use for a film area or roll film. I stick my jugs of chemicals in warm water if washaidd are too cold, or cold water if they are too warm, water from the tap that is. A drop of dishwashing liquid will also do just fine, but common sense tells me to avoid the more heavily perfumed or brightly coloured brands.
Your negative will look like a very big grain negative and this process is then irriversable. To be honest today with modern film you can probably go from developing at 20 degrees C straight to wash at 5 degrees C. Before you know you’re lost in too many parameters and possibilities. If the running water temp is say 5 degrees C, what I do is reduce the film temp in stages.
Hello, I recently purchased a bottle of Ilford Wash Aid to act as a hyper cleaning agent after using the fixer. I cast my vote of “No”, but not because I think it’s generally unnecessary; rather I use a non-hardening alkaline fix and, according to the instructions, use of a wash-aid is unnecessary. Perhaps another marketing ploy to get the stuff off wasahid shelves?
However, the Ilford Wash Aid is in ready to use liquid form. Do you already have an account?
One thing I can think of that would limit the dilution would be the possibility of exhausting the developer before the desired level of development is complete. Comming back on one of above remarks: Futher most films are loosing some effective film speed in Rodinal so that means you have to shoot your film on a lower iso rate. I’m gonna develop try to! You don’t want too short a time as otherwise the pouring time becomes significant and the washaic thing becomes more time critical.
