I try to wash my makeup brushes as regularly as I possibly can but it is not always that easy. Before using this brush cleaner I used to just clean using my hands and thought they were clean...that was until I started using this. It works SO MUCH BETTER. My brushes get a deep clean now and they feel much softer. They also drier faster for some reason. I will not clean them without my egg again. I just wish the surface was bigger though.
