You will need:
- Hat
- Large Tupperware Container
- Dry Detergent
- Water
- Blender Bottle Shaker Ball (optional)
- Take a leak proof Tupperware container.
- Place your hat inside. Add 1 teaspoon dry detergent.
- Fill with warm (not hot) water until the hat is over halfway covered. Make sure to leave some space for the water to really move around.
- Close lid and shake. You will immediately see the dirt and grime come into the water and make it turn brown.
- If you need to get a stubborn sweat line out of the hat brim (let the line soak in a thin layer of DAWN soap overnight first) !
