> RelyOn Multi-Purpose Disinfectant Cleaner

Over the years, rebreather divers have used many products as breathing loop disinfectants and cleaners, often with questionable safety, uncertain efficacy, and poor material compatibility. In 2002 at the request of the Canadian Forces diving community, Defence Research and Development Canada report studied nine different disinfectants: Advance TBE, BI-Arrest, Buddy Clean, CaviCide®, Confidence, Listerine® Antiseptic, Sanizide™, TriGene II, and Virkon®. They concluded that only one, Virkon, could be primarily recommended for disinfecting rebreathers.

Virkon was developed and is manufactured at the Antec International facility in the UK, which became a DuPont company late in 2003. Virkon's most common "S" formulation is used primarily in veterinary/animal livestock applications. DuPont changed the name of the Virkon formulation suitable for human use to be RelyOn™ Multi-Purpose Disinfectant Cleaner. RelyOn MDC is manufactured under more strenuous production controls and quality assurance testing, making it suitable for human use.

Product Features
  • RelyOn MDC is effective against a wide range of viral, bacterial, and fungal pathogens including Influenza, HIV, Hepatitis A, B and C, MRSA, VRE, RSV and Norovirus (Norwalk-like virus).
  • RelyOn MDC contains a surfactant and will clean and disinfect in one step.
  • RelyOn MDC 1% solution is non-irritating to skin and eyes on incidental contact as well as less corrosive to environmental surfaces.
  • RelyOn MDC, when used as directed, is compatible with rebreather materials and will not harm elastomer O-ring seals, counterlungs, corrugated hoses or any other components in the breathing loop.
  • RelyOn MDC is available as a space-saving dry concentrate in the form of an effervescing tablet, avoiding the leakage problems of transporting liquids.
  • RelyOn MDC is pleasant to use with a faint lemon odor.

Directions for Use

RelyOn MDC is available in tubes of effervescing 5-gram tablets along with a 16-ounce convenience spray bottle. To use, add one RelyOn MDC 5g tablet to 16 ounces of ordinary drinking water to prepare a 1% solution. Follow the recommendations from the rebreather manufacturer for disinfecting and cleaning your rebreather, allowing the solution to contact surfaces to be disinfected for 10 minutes and then rinsing with water.

Storing Relyon MDC Tablets and Solution

Don't get any water in the tablet bottle, make sure your hands are absolutely dry when dispensing a tablet from the container. We've noticed that if the Relyon MDC tablets are not stored in an airtight manner, over time the tablets will react with the moisture in air, breaking down and starting to dissolve right in the container. There is a small packet of desiccant in the container with the tablets, be sure to leave it in place on top of the tablets during storage and take care to make sure the cap is tightly closed. Some people place the container in a zip lock bag or transfer the tablets to a more airtight container like a pill bottle. The problem is more pronounced with the 50 count bottle because most people will take much longer to use up the larger quantity. If you purchase the 50 count bottle, we suggest using it to refill a 10 count bottle or other smaller airtight container and then put the large bottle back in a ziplock bag, suck out the air and store it in the refrigerator.

The Relyon MDC solution has a color indicator to assure potency, when the solution turns clear it should be discarded. We've noticed that the Relyon solution will lose potency faster when the temperature is higher. If you leave the spray bottle out in the hot sun, it will turn clear in just a couple of hours. If you store indoors it will last a few days up to a week or two depending on the room temperature. If you store the solution in the refrigerator it will last quite a long time.

Beware of Repackaged Lubricant: Some other vendors are purchasing oxygen compatible lubricants in bulk containers and then repackaging it in smaller 1/4 oz or 1/2 oz sizes. Aerospace Lubricants has advised us this is an unapproved and possibly unsafe practice. These unapproved package types contain mold release agents, silcone treated rubber stoppers in the syringes, and dyes in colored containers; all of which can leach into the lubricant itself. These containers, along the repackaging conditions themselves, are certain to produce lubricants which are contaminated and no longer suitable for oxygen service. Dive Gear Express only sells lubricants that are supplied directly from the factory in their carefully selected packaging.

DeoxIT GOLD GN5 Contact Cleaner/Conditioner, 14g Mini-Spray

DeoxIT GOLD is excellent for maintaining the electrical contacts of your dive computer I/O port and cable, as well as the battery contacts and sensor connectors in your rebreather. DeoxIT® GOLD (formerly known as ProGold) was developed by Caig Laboratories for the aerospace industries and is especially well suited to critical low current applications. DeoxIT GOLD is a unique conditioning agent that improves conductivity and provides long-lasting protection. DeoxIT GOLD is designed to dissolve small amounts of oxidation, and suitable for delicate gold plated contacts and connections where only slight cleaning action is appropriate. DeoxIT GOLD is non-abrasive, non-corrosive, non-toxic and environmentally friendly.

We offer DeoxIT GOLD GN5 in a 14g mini-spray 5% solution with non-drip applicator (approximately 75+ applications when used as directed), a convenient quantity and package for use with your rebreather.

Cleaning Low Current Electrical Contacts

Always use cleaners specificly designed for the precious metal contacts used in low current applications found in high-tech electronics. The low current makes the contacts exceptionally sensitive to contamination yet their ultra thin precious metal plating is easy to damage during cleaning.

Never use the cleaners commonly associated with SCUBA maintenance. Many such cleaners contain solvents that are polar and also may leave residues, making them a potential problem in low current applications. This is also true of many household products such as rubbing alcohol.

Never use ordinary 'tuner cleaner' products for cleaning precious metal contacts, particularly with rebreathers. Their cleaning action is too harsh and most formulations sold by consumer electronics retailers contain petroleum distillates, which are flammable and not safe for use with some plastics.

Never use silicone based cleaner/lubricants with electrical contacts, even though this is an often suggested practice. Silicone products will react with plastics and other contaminates to form insulating films and silicone carbide compounds which can cause intermittent connections.

Never use a pencil eraser to clean precious metal contacts, even though this is another common practice. Erasers are highly abrasive and will remove the ultra thin precious metal plating. Further, the glue in erasers leaves behind a film that is extremely difficult to remove and can also cause intermittent connections.
