How old are they? How much use have they seen? Any visible pigment buildup near the ferrule?
Einion
Or it could be W&N giving you the finger.
Sorry but in my years of painting, I have not been impressed with the brush quality.
Thanks Karrie; needed the chuckle at the moment.
I
love my W&N's, but I'm not blind to the fact that some of them have been of really duff quality. Fortunately none of mine have, but I cherry pick mine with care.
As for rescuing them, well if there is stubborn paint gunck (technical term) there are two harsh methods;-
Acetone (or el cheapo nail polish remover) place a little of this in an eggcup and scrub the brush around to break up the residue, then spend the next hour or two washing the brush carefully with proper brush soap. (and for the love of all things holy DO NOT lick your brush with Acetone on it, unless you want to spend a couple of hours with the room spinning and feeling completely F****d up.
My T-shirt for that piece of stupidity fits perfectly.)
Dettol: do the same.
Both of these methods will clean the crud out of your brushes......But can reduce the lifespan if you don't take proper care of the brush afterwards.
Here's a link to some brush soap from the S.A.A
