First they make the most of how their brushes are clean, handpicked,
superbplasmacoated or what, and then they recommend mild detergent, or
simple mild soap?!?
AFAIK all wetting agents are quite aggresively leaving _unremovable_
gunk on plastic or steel. As anybody who has used darkroom will tell
you. Simply from the wetting agent in last step of B&W developing, old
plastic or steel reels develop a layer of the agent, which is
impossible to remove, and increases friction a lot.
Actually, reel manufacturers like Jobo recommend removing the film
from the reels before putting it in the wetting agent, so the reels
don't come over and over to contact with it...

;-) My father is a painter, and all his brushes have wooden handles
;-))) (OTOH, he likes camel-hair brushes the best, these I won't
borrow for the cleaning <g>)
Good light!
