There are a few things you can do to clean a makeup bag before you use it:

  1. Remove all of the makeup and any other products that may have been inside the bag. This includes foundation, blush, mascara, and other cosmetics.
  2. Use a mild soap solution to clean the inside of the bag using a circular motion. Make sure to get all of the dirt and debris out of the bag.
  3. Rinse the bag with water and then dry it off using a towel or air-drying method.
