I just cleaned all of my shaving brushes. I clean them every 6 months to remove dirt, oils, and soap residue. A number of my brushes are of vintage age, and I think the cleaning may extend their useful life. I use either MAC Brush Cleaner or Neutrogena Anti-Residue Formula Shampoo with tepid water, scrubbing the brush on my palm to build up a 'lather' before a tepid tap water rinse and a final soaking rinse. About every couple years I apply a hair conditioner.
Do you clean your brushes?
