In this tutorial, we learn how to make homemade makeup brush cleaner. First, grab an empty spray bottle and add in 1 c water to it. Next, pour in 1/4 c alcohol to the water. Now, pour in 2 tbsp of dish soap to the mixture along with 1/2 tbsp baby shampoo. After this, add in 1 tbsp of leave in conditioner to the mixture. Now, stick a straw into the bottle and mix everything around gently. Don't create a lot of soap on top by mixing it too hard. When you are done with this, you can spray it onto your makeup brushes to clean them!
