An apparatus and method for preparing a pH balanced saline solution and using the saline solution for rinsing tissue. The apparatus includes a container having flexible sidewalls and an opening for a removable cap. The cap has a rounded convex upper portion curving away from an opening at the cap's uppermost surface and has a conduit in the cap's interior, which conduit extends into the container when the apparatus is fully assembled or is connected to a tube that extends in the container. A saline solution is prepared by adding sodium chloride and sodium bicarbonate to distilled or boiled water. The sidewalls of the container are compressed to urge the saline solution through the conduit, or tube and conduit, and through the opening in the cap. The solution can be used to rinse tissue, such as a mucus membrane, eye tissue, skin or tissue inside an oral cavity.
