Hey Loris,

Well, I meticulously cleaned my brush, too-- and the first time I did
it, no problems-- after a very few repeated uses (both cyanotype and
pt/pd with the same brush)-- even after cleaning very carefully-- I
would get some slight discoloration, from the contamination. Not all
that visible, but I could see slight streaks-- very subtle-- but
under the right light, I could definitely see it.

Brushes (even the famed magic brush) are probably the least expensive
part of what we (I) do, so why not just buy another and avoid the
potential contamination and headache.

I also agree with the poster who said they use a cheaper brush for
the cyanotype coating. I do as well. In fact, I have a slew of
cheap brushes that work perfectly fine for me. I use the Richeson
only for pt/pd, which really does seem to make a difference-- for
that particular process.

Diana, what problems did you experience? I put the brush in a vessel
filled with water right after coating. I wash it later when the
print is
exposing. Never encountered any problems that way!?

...I was never able to clean the cyanotype
sufficiently enough to not cause a problem when coating pt/pd with
that same brush...
