Steramine is an antimicrobial agent for use on hard non-porous surfaces against a wide range of pathogens including HIV-1 and CA-MRSA. The active ingredient in Steramine, quaternary ammonium, is on the EPA list of antimicrobial agents that meet their criteria for use against SARS-CoV-2 (COVID-19 novel coronavirus). Steramine has a long history of use that meets the public health and regulatory criteria of the Environmental Protection Agency (EPA), U.S. Public Health Service (USPHS), and the U.S. Food and Drug Administration (FDA).

Steramine is also a cationic surfactant to both clean and sanitize your dive equipment in one step. Unlike bleach, Steramine sanitizing solutions are non-irritating to the hands, non-corrosive to metals, non-staining, and odorless. Among the EPSO team members, our many years of experience with Steramine has demonstrated the sanitizer has no compatibility issues with any of the materials commonly seen in diving equipment such as rubber, silicone, neoprene, plastics, mask optical coatings, chrome plated brass, aluminum, and stainless steel.

We offer a container of 150 tablets making a total of { 75 to 150 gal | 284 to 568 L } of sanitizer depending on the desired concentration of 200 ppm for soaking or 400 ppm for spraying. The dry tablets themselves do not have a shelf life (the date on the bottle is date of manufacture not expiry) because the antimicrobial agent is only activated once mixed with water.

Directions: Use ordinary drinking water to prepare your sanitizing solution. Mix one tablet (for 200 ppm) or two tablets (for 400 ppm) with one gallon of water. (Steramine tablets can be slow to dissolve in cold water, so if you need to accelerate the process then dissolve the tablets in a cup of warm tap water and then pour that into the rest of the cold water.) Do not mix with other detergents or soaps. EPSO recommends the stronger 400 ppm concentration if you are spraying and the 200 ppm concentration if you are soaking. Follow the recommendations from the equipment manufacturer for cleaning your dive gear, allowing the wet solution to contact surfaces to be sanitized for at least 1 minute. You should not soak dive equipment in hot water and we do not recommend prolonged (i.e. multi-hour) soaking. Steramine leaves no residue, but we recommend rinsing after use. Unless you use a test strip to validate the solution strength, you should prepare a fresh sanitizing solution daily or if the solution becomes diluted or soiled.
