    I use a Silverprint archival washer. They don't come with instructions - or at least mine didn't and yes, I had the same problem getting the hoses to fit the taps! The paper emulsion should face the textured side of the dividers. Rotating prints during the wash sequence is good practice; I rotate once 180o degrees halfway through. Martin Reed (of Silverprint) wrote an extremely interesting article entitled 'Mysteries of the vortex' which refutes some long held beliefs about archival washing. I have a copy of it somewhere. As a previous poster says, you don't need copious amounts of water to wash a print - too strong a water flow may even reduce washing efficiency - just a moderate flow will suffice, say 1.5 ~ 2 L per minute max. Personally, I use a fill and dump method on my prints. 6 ten minute soaks in water at 25~30c (preceded by an initial quick wash and a 10 minute soak in home-made washaid). Anyway, don't worry, they're very well made and do the job admirably.

    Mysteries of the Vortex, the title of the article.
    Martin included in that Photo Techniques detailed
    view of print washing a picture of the 12x16 Nova
    washer. A huge dead spot exists center. Due at
    least in part to the 6 liter per minute wash
    water input.

    He goes on to describe a three change soak
    method. Very little water and very clean results.
    I've found alternate tray still water soaks to do
    very well. Separators make of my method
    a horizontal slot washer. Dan

    I am going to read this article tonight.

    One more question I have is that I have the washer in another room in the house. So during a printing session I keep prints in a holding bath of water until I have 5 or so ready for washing. I then transfer these to the washer in the other room. Would it help/be harmful if I put some hypo clearing agent in the holding bath? Is it going to damage the prints if they are left in the holding bath for too long?

    If your routine is; last fix, rinse, hca, hold, then water
    alone should do. If your routine is; last fix, hold, then
    better use some hca. Commercial hca's are near
    neutral ph and should not soften the gelatine.

    I routinely have prints soaking 12 to 15 hours;
    an overnight soak. Dan

    Thanks, Dan.

    I also just read the 'Vortex' article and HCA is obviously a no brainer.

    That article is a very interesting read.
