Using the M-Pets Soap Dispenser & Brush is easy. First, fill the dispenser with your pet's shampoo. Then, when you're ready to bathe your pet, simply press the button to dispense the shampoo onto the brush. Start gently brushing your pet's coat, moving the brush in the direction of hair growth. The rubber tips will help create a good lather and remove dirt. After the bath, you can also use the brush on your pet's dry coat to clean it further. As for maintenance, rinse the brush thoroughly with water after each use to remove any remaining shampoo and dirt. Let it dry completely before storing it. Keep in mind that the color of the brush you get might be different from what you see in pictures, but the function remains the same.
