I'm careful about not soaking BHR pens in water, but BHR sections/feed/nibs do need to be cleaned and flushed. Even when they start out looking perfectly black, they always seem to discolor when I try to flush them, even after the slightest contact with water.
Ideally, I'd put the sections briefly in the ultrasonic cleaner, but then discoloration seems guaranteed.
Is there anything to be done about this problem?
I know I can work on the section with micromesh, etc., to restore the color, but it would be nice to avoid the problem in the first place.
Besides, sections do have to come into contact with ink, so they seem bound to discolor.
Suggestions appreciated.
