It's quite simple, I tried to review elf's make up brush cleaner and that was pointless. Straight garbage, but it said I have to wash each brush individually. As a busy woman that I am I don't have time to wash 20 something brushes individually. What I used after the elf cleaner did not work is the Johnson's Baby shampoo & Mac's facial cleaner (Green Bottle).
Literally take a cup, fill the bottom with half & half of the soaps and then fill the cup half way with water.
Place the brushes in the cup. I leave the brushes for 10mins, but my brushes really needed Jesus, so I left them in this time a bit longer. Swivel the brushes around, and then rinse out.
Make a flat paper towel bed and then lay the bushes to dry.
That's all folks
