Directions Alkalol is intended for use at variable strengths depending on personal preference and thickness of mucus. We recommend starting with a mild dose and adjusting according to preference. Mild: Add one teaspoon of Alkalol to the Alkalol Nasal Wash Cup, filling it approximately 20%, and the balance with saline or warm distilled or sterilized water. Medium: Add two teaspoons of Alkalol to the Alkalol Nasal Wash Cup, filling it approximately 40%, and the balance with saline or warm distilled or sterilized water. Strong: Add three teaspoons of Alkalol to the Alkalol Nasal Wash Cup, filling it approximately 60%, and the balance with saline or warm distilled or sterilized water. Extra-Strong: Add four teaspoons of Alkalol to the Alkalol Nasal Wash Cup, filling it approximately 80%, and the balance with saline or warm distilled or sterilized water. Alkalol is formulated to be refreshingly strong. Upon initial use, you may experience an invigorating sensation lasting a few seconds. This sensation is part of the process that allows Alkalol to work.
