Disinfectant, Lubricants, and Contact Cleaner for Rebreathers

• 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.

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.
