The Soap Opera Continues The Soap Opera Continues

Water, water everywhere, but is it any good from the sink?

25 Jan


Do you know what’s hiding in your tap water?

"Is it hard, soft, iron rich, or smelly like rotten eggs?" "How does water quality affect cleaning chemistries, and what can be done about it?" "And how can high purity water contribute to more effective cleaning?"

Certainly, water is important for the final rinse, but what about in the formulation of the cleaning agent itself and in the cleaning stages of instrument processing? We all know that water is finite, but not all water is created equal. That’s why advertisers and soft drink marketers have capitalized on “pure water”, offering so many versions of good “ole” water that we can become totally confused about which to choose.


Di-hydrogen mono-oxide

Better known as water is rarely found in its pure state. Despite it being a universal solvent, there’s always something mixed up in tap water or “potable” water as it is sometimes called. This is where chemicals, detergents, enzymes, and chelating agents are added to the script of our “soap opera” as supporting characters that are critical to the outcome.

To ensure quality, the federal government regulates tap water. The Environmental Protection Agency (EPA) sets standards for both tap water and ground water. That means that in most cases, tap water will be free of common contaminants, such as pesticides, chemicals, and heavy metals, with an acceptable pH around neutral.

Let’s take a closer look

To make water safe to consume, a treatment plant must filter out particulates, disinfect the water to kill microorganisms, and remove any minerals or other chemicals that exceed the standards set by the EPA. It is convenient to turn on a faucet and have potable water whenever you want it. Tap water is inexpensive, costing a fraction of a penny per gallon. However, is tap water safe for consumption and for cleaning medical devices? If you are worried about contaminants, and you should be, consider Flint Michigan. This is a very concerning, but a rare exception. Thanks to municipal water treatment facilities, the water that comes out of the faucet is considered safe to drink. To remove microorganisms from water, treatment facilities add chlorine or other chemicals to sanitize the water, giving it a “swimming pool” odor. Additionally, some water is “hard”, meaning it has a higher concentration of minerals that are harmless to drink, but clog pipes and leave a white residue on devices.


Water Treatment for Instrument Cleaning

When developing a script there is always an antagonist and a protagonist. In our soap opera the antagonist is an unnecessary element added as a benefit but does more damage than it’s worth. Our hero is a simple solution to filter and remove all the bad stuff without adding anything into the mix. RO is typically used as the final rinse in healthcare facilities. What if we change the scenario and begin the cleaning process with RO treated water? Now, the detergent can go right to work without having to tackle water borne impurities. We have conducted numerous studies that show increased effectiveness when RO water is used for cleaning as well as rinsing.

Use a validated, Safer Choice labeled detergent where RO water is the solvent and RO water is used for cleaning and rinsing. We do this at Case Medical, where we see consistent excellent outcomes every day for manufacturing and for cleaning of product and plant. No residue, no salt deposits, no discoloration. RO water treatment is our method of choice for manufacturing, for use in our autoclave, and RO water is the solvent in our Safer Choice labeled instrument chemistries whether the detergent is  enzymatic or not.


Case Medical, a US EPA Safer Choice Partner of the Year formulates, manufactures, and recommends a validated, pH neutral, low foaming, multi-enzymatic detergent, as the protagonist in fighting grime and bioburden. So if you have hard water, use a detergent with active chelating agents to follow the enzyme wash step, and provide even better results. Case Medical is here to help you find a cleaner that meets all your specifications and it may only take one.
