How to Clean Your Brush On Block® Mineral Powder BrushUpdated 3 hours ago
Keeping your Brush On Block® mineral powder sunscreen brush clean helps it perform its best and ensures smooth, even application every time. These instructions apply only to your self-dispensing mineral powder brush, not to the Sheer Genius Brush, which is designed for applying lotion.
When to Clean
If your brush looks full but isn’t dispensing powder easily, it’s probably time for a cleaning.
Quick Clean with Brush Cleaner
For routine maintenance, use a gentle brush cleaner:
We recommend a deep clean when your brush is empty and ready for a refill. If you need to clean it sooner, first pour out any remaining powder onto a clean piece of paper or Ito a clean container.
If water gets inside the brush during cleaning and powder clumps form, you can easily fix it. Find the small white tube in the center of the bristles and gently insert a straightened paper clip to break up any clog. Your brush should then dispense powder normally.
Keep It Fresh
