So what the best way of cleaning the brush after use and where to store while it drys?
...I think Simpson say that their brushes can be stored with the loft up, however should I own a Simpson I would still use the stand.
+1There is no consensus on storing a brush in a stand with the hair facing down or storing it sitting on its handle with the hair facing upward. Just rinse it well under warm water, gently shake it out, gently dry the tips on a dry towel (see this mantic59 video on YouTube), then store it whichever way, up or down, allows you to sleep at night.
