The Seaview 180° can be safely washed using warm water and soap. Avoid using grainy or coarse soaps and detergents. Also be sure to use a soft cloth to avoid scratching the lens. Once you have thoroughly rinsed the mask, hang dry it out of the sun. You may also dry the lens and frame with a soft towel.
IMPORTANT: Rinse your mask after each use in salt water to reduce odor build up.
