To keep spoolies clean, follow these simple steps. Firstly, wet the spoolie with warm water. Then, apply a small amount of mild soap or shampoo to the bristles. Gently massage the soap into the bristles, ensuring all areas are covered. Rinse the spoolie thoroughly with warm water, making sure all soap residue is removed. Use a clean towel to pat dry the spoolie or let it air dry naturally. It's important to clean spoolies regularly, especially if they come into contact with makeup or oils. By keeping spoolies clean, you'll ensure that they remain hygienic and free from bacteria, making them safe for use on your lashes or brows.
