#6 Brush Saver: The last bottle is for cleaning brushes between and during applications, dissolving any leftover powder. It maintains a soft and clean brush during applications. Instructions: To use the Kiara Sky Brush Saver, remove the dirty/used brush that you would like to clean and wipe off all excess product. Repeat this step with the Brush Saver brush. Swap the brushes so that the dirty/used brush is now soaking in your Brush Saver bottle. Leave these closed for at least 15 minutes before swapping the caps/brushes back to their appropriate bottles. Here is a video explaining these steps! "Get stronger, lightweight and natural long-lasting nails with our easy-to-use dip powder and dip essentials.
