Baby shampoo/dish soap or whatever you prefer
2 small bowls
What I do:
I mix about a tablespoon of olive oil in with about 5 tablespoons of baby shampoo into a bowl. The one I found on Pinterest said to mix equal parts of oil with soap, but I found that too much oil made it very hard to get rid of the oil and it made my makeup weird for a few days. So I use less.
I then fill up the second bowl with warm water.
I take a dirty brush and first run it under warm water and swirl around the first bowl with the soap/oil mixture. Swirl around the bottom of the bowl for about 15-20 seconds. I will then cup the palm of my hand and swirl it around the palm of my hand to get any deep makeup out of there, and then do the same thing in the second bowl of water. If the brush is still dirty, I dip back in the first bowl until clean. I’ll then run the brush under warm water to get everything off and then gently press the excess water out and reshape the brush.
Once I’m done with all of the brushes I store them facing down overnight in a clean towel to let all of the water drip out of them. If you store upright it will deteriorate the glue in the handles of the brushes.
That’s it! I like using the tiny bit of olive oil in with my baby shampoo because it really makes my brushes soft and gets them clean.
I also use this mixture for my beauty blender and as you can see, it gets it completely clean.
