Step 1: Take a piece of a paper towel and fold it in half, and then in half again.
Step 2: I love the MAC Brush Cleanser! It is $15.00 at the MAC store, both in stores and online! It is a good sized cleanser that will last months at a time. It is well worth the price!
Step 3 & 4: Take the brush you wish to clean and swirl it in a circular motion. Do this lightly! You don't want to press down too hard! The brush I chose to clean what my MAC 168 Large Angled Contour Brush, which I use for both my powder and my cheeks! Continue this process until there is no longer an excessive amount of makeup on your brush!
The best part about this routine is that your brushes will dry so fast! I have never come across another brush cleaner that will dry my brushes in just minutes!
