Darkroom Supplies - FPP Archival Permanent Wash (1 qt)
FPP Archival Permanent Wash (1 liquid quart concentrate)
For Black & White Negatives
Using an archival wash with your films and papers not only saves you over 90% water usage but guarantees your images will last the test of time.
The time and water savings are substantial (film wash times can be cut from 1 hour to 3 minutes!)
Mix 1 Gallon - Use 3 ounces of product concentrate to make to make one gallon of long lasting working solution. You can pour back and reuse your working solution for up to 3 months.
The capacity per gallon of working solution is 75-100 rolls/sheets of film.
Mix 1 Quart - use .75 oz (22ml) per quart. Follow the directions on the bottle for mixing and use. It will last 3 month in a closed container, and will treat approximately 18 rolls of film.
Q: Is this the same as "Hypo Clearing Agent". Can I use FPP Archival Wash instead?
A: (From FPP's Leslie Lazenby) Yes you can use FPP's Archival Permanent Wash instead Hypo Clear. It's economical, does a better job and is much more long lasting.
- Economical; it takes just a few ounces to make a gallon. The time and water savings is amazing. Your wash time of 30 minutes to one hour is reduced to 3 minutes. That's a lot of water!
- Long lasting; on the shelf or mixed it exhausts by use not by oxygen exposure.
- Gets the job done; I've used this formula for 40 years and my negatives still look great. My predecessor used it before me and I have all of his negatives dated to the 1930s. All perfect. I looked into other version of Hypo Clearing agent and found they did not have all these qualities. It truly is a superior product.
Q: I am curious if it is possible to use your permanent wash solution with c41 development?
A: (From Leslie Lazenby) Permanent Wash is a B/W film product only. B/W film is primarily silver and color is primarily dyes. It works on releasing the unused silver to speed up the wash time and keep any residual silver from surfacing later. Color film can have a shift or fading in dyes, but there is currently nothing available to extend the life of these negatives except good processing habits.
