All Bleach is NOT Created Equal! Knowing exactly how to use bleach correctly can disinfect surfaces or purify water. Knowing which bleach contains harmful additives and chemicals, and thus must be avoided, can save your life.
Recently at one of our area Preparedness Meetings, we had the opportunity to learn from an active member of our group. Craig is a Registered Nurse with a background in critical care and emergency leadership. He had recently completed updated training for infectious diseases and modern-day epidemic mitigation, including new Ebola protocols.
Craig was kind enough to share much of what he learned with our group. The topic of using bleach for disinfecting or purifying water has been widely spread throughout the preparedness community. However, Craig shared information that I had not seen mentioned much in detail. I found it important and wanted to share it with readers of PREPARE Magazine.
All bleach is widely acceptable as an antimicrobial and can kill microbes on hard, non-porous surfaces. Bleach seems to be the go-to disinfectant for everything from bathrooms to kitchens. In an emergency situation, it is often promoted as a method for purifying water.
For surfaces that may have become contaminated, or when dealing with a contagious individual in the home, treating an area correctly can be life-saving. But only if it is performed properly with the right bleach, in the correct ratio, for the full length of time, and dried in the appropriate method.
What’s Wrong With Some Types of Bleach?
When it comes to bleach, you cannot just “grab a gallon” and go. You need to read the label carefully. “Regular” bleach is the only kind you want for disinfecting surfaces or treating water, not any of the other formulations.
If there is anything other than the word “Regular” describing your bleach, relegate its use to laundry only. Thick-cling, splash-less, and scented varieties contain harmful additives that can create as much harm as the untreated surface or water.
Splash-less bleach is not simply splash-less because the spout is shaped differently. The manufacturer has added a soap or sudsing agent to change the viscosity of the liquid bleach, making it easier to pour.
Thick-cling bleach contains even more of these additives than its splash-less counterpart. If you have ever used these products, you may notice a soapy film on the countertop surface or more suds in your washer. This can be harmful if swallowed and may contribute to asthma and respiratory issues.
Scented bleach has become popular for laundering. While some people may not notice problems when using it in wash water, dyes and perfumes can have a negative impact when used on utensils, countertops, or in drinking water.
These additives may be hazardous to the digestive system and may also cause skin irritation, allergies, asthma, respiratory problems, and other health concerns.
Which Bleach Is Safe For Emergency Water Treatment?
Regular bleach is the bleach product that should be used when bleach is needed for disinfecting or emergency water treatment. Avoid scented bleach, splash-less bleach, thick-cling bleach, color-safe bleach, or any bleach with added cleaners, fragrances, soaps, or other additives.
Proper Disinfecting Time and Technique
Two teaspoons of Clorox Regular Bleach in one gallon of water will kill germs, but only if it has been in contact with the hard surface for two full minutes and is then allowed to air dry without rinsing.
Important Safety Considerations
Regular bleach is a widely used cleaning method. It should be noted that this is not the only option for disinfecting, but it is one of the most widely accepted when used properly.
Even regular bleach has drawbacks. Bleach is caustic, may cause eye irritation and gastric burns, and can be corrosive to metals in high concentration or with long exposure.
For long-term storage, regular liquid bleach may not be the best option. Compared with some other disinfectants, bleach is relatively unstable and has a limited shelf life.
Please share so we can all help each other be better prepared. Thank you!
Final Thoughts
Not all bleach products are suitable for emergency sanitation or water treatment. Only regular, unscented household bleach should be considered for those purposes, and proper dilution ratios, contact times, and safety precautions must always be followed.
Understanding the difference before an emergency occurs can prevent serious health risks and make your preparedness plan more effective.
Popular Questions
What are the dangers of using scented bleach for cleaning?
Scented bleach contains dyes and fragrances that can be harmful when used on surfaces like countertops or utensils. These additives may lead to skin irritation, allergies, and respiratory issues. It's crucial to avoid using scented bleach for disinfecting, especially in areas where food is prepared or consumed.
Why should I avoid thick-cling bleach for disinfecting surfaces?
Thick-cling bleach has added soaps and sudsing agents that can leave a soapy residue on surfaces, making it unsuitable for disinfecting. This residue can be harmful if ingested and may contribute to respiratory problems. For effective disinfection, stick to regular bleach without these additives.
How can I ensure I'm using the right bleach for water purification?
To purify water, always use regular, unscented household bleach. Avoid any bleach that has added cleaners, fragrances, or other additives, as these can be harmful. The correct ratio is two teaspoons of regular bleach per gallon of water, ensuring it sits for the proper contact time to effectively kill germs.
What should I look for on a bleach label to ensure it's safe for disinfecting?
When selecting bleach for disinfecting, look for the word "Regular" on the label. Avoid any formulations that include descriptors like "splash-less," "thick-cling," or "scented," as these contain harmful additives. Regular bleach is the safest option for both disinfecting surfaces and treating water in emergencies.
Can using the wrong type of bleach lead to health issues?
Yes, using the wrong type of bleach can pose serious health risks, including respiratory problems and skin irritation. Additives in non-regular bleaches can be harmful if they come into contact with food or drinking water. Always choose regular bleach for disinfecting and follow proper usage guidelines to minimize health risks.
