DIRECTIONS:

Put some warm water in a sink. Add some baking soda and swirl to dissolve. Put all dirty combs and brushes in to soak. Dirt and oils will lift out. If spray or gels are built up, run combs back and forth through the brushes submerged in the baking soda solution. The combs clean the brushes and the brushes clean the combs.
