Try using slightly warmer water or extending the time or both. This
veiling may also be the result of the chromium image or stain. (Does it
look pale green to tan?) Clearing in 5% potassium or sodium
metabisulfite solution will remove this chromium image/stain if that is
what it is.

To take a break from all the RGB/CMY discussion I have a question to all
experienced gum printers (and others that just like to experiment). I
would like to develop my gums to a crisp white. I sieze my papers, so I
don't get any stain, but there is usually a very thin vail of color
I can rub it off with my finger, or a brush, but this is very crude. I
have been using a shower head to clear the highlights, but that tends to
leave a grainy look. I am wondering if others have tried other methods
"forced" development, like maybe sawdust, or even sand in the tray. Any
chemical means to accomplish that?
