Review (5/5): This is the greatest invention I've stumbled upon
Even with various gloves and pads, washing makeup brushes is always a pain. You always get your hands wet and prune-y.
This is the greatest invention I've stumbled upon. It's very easy to choose a boot, insert your brush, and spin wash. I used this to clean ALL of my makeup brushes and it worked well for almost every single one. Each brush needs to be positioned a little differently for optimal cleaning depending on the shape and length of fibers. The only brushes that didn't work well were bulky face brushes with heavy handles that the machine did not spin well and small eyeshadow and detailing brushes that couldn't fan out. I recommend two rounds of rinsing. The first in soapy bubbly water to clean the brushes and the second in clean water only to rinse out any bubbles and residue.
Even with two cycles, the process was quicker and less intensive than washing by hand and the drying time was cut down to almost nothing for nearly all my brushes, including dense synthetics.
I highly recommend!
