Application: Heat clean water to 38-40 degrees. Mix with preservative and iodine-free salt (1 liter of water - 3-4 grams of salt). Fill the nasal wash bowl with salt water. Lean forward, tilt your head to the side and back slightly. Breathe through your mouth throughout your nose wash. Insert the spout of the nasal lavage vessel into the upper nostril so that the water drains through the lower nostril. When the water has flowed through, turn your head to the center, allowing the water to flow out of your nose. Repeat the process for the other side as well. Then, leaning forward slightly, breathe alternately through one and then through the other nostril. Exhalation is strongest.
