normal mild wash replaces brush cleaners

You don't really need to buy those blood-suckingly expensive brush cleansers for your makeup brushes.
I find that a normal mild hand wash, facial cleanser or baby shampoo will do the same, for a lot less.
Unless, of course, u bought Sonia Kashuk or Kevyn Auctoin brushes, u would naturally want something on par with the brushes' standard to cleanse them, right?
If not, the economical way would be normal mild body wash or facial cleansers.

Have fun!
