What Are Disinfectants?
Disinfectants are chemical agents formulated to eliminate harmful germs, viruses, and bacteria on surfaces and objects. Popular disinfectants include bleach solutions, alcohol-based products, and hydrogen peroxide formulas, all proven to kill a broad spectrum of pathogens effectively. It’s important to note that disinfectants kill germs but do not remove visible dirt or debris, so cleaning surfaces prior to disinfecting ensures the best results.
What Surfaces and Objects Should You Clean and Disinfect?
To effectively reduce the spread of infections, regularly clean and disinfect high-touch surfaces and frequently used objects. These include light switches, doorknobs, faucets, countertops, toilet handles, children’s toys, and electronic devices such as TV remotes, smartphones, and keyboards. Regular sanitation in homes, offices, schools, and public spaces plays a critical role in minimizing germ transmission.
Introduction to Sanitizers
Sanitizing refers to reducing the number of germs on surfaces to a safe threshold defined by public health guidelines. This level is typically a 99.9% reduction in bacterial presence and is achieved through cleaning, disinfecting, or both. Different hygienic practices cater to specific needs—for example, mopping floors with appropriate chemical solutions, sanitizing dishes in dishwashers, or wiping electronics with antibacterial wipes to lower contamination.
Many modern cleaning products now combine cleaning and disinfecting properties, simplifying the process and enhancing infection control.
Summary: Cleaners remove dirt and impurities from surfaces; sanitizers reduce bacteria to safe levels; disinfectants kill a wider range of microorganisms, including viruses and fungi, ensuring higher sanitation standards.
Where Are Germs Found and Why Should You Clean Them?
Germs are everywhere—existing in water, air, soil, on our skin, and inside our bodies. They also accumulate on surfaces and objects we frequently touch. For example, items like TV remote controls, smartphones, and keyboards often harbor significant numbers of microorganisms. Touching these contaminated surfaces and then touching your face can introduce harmful germs, increasing infection risk. Although some microbes are beneficial, many can cause illnesses, making regular cleaning and disinfection essential.

Frequently Asked Questions (FAQs)
What is the difference between cleaning, sanitizing, and disinfecting?
Cleaning involves removing dirt, dust, and visible impurities from surfaces, which also helps reduce germs. Sanitizing lowers the number of bacteria on surfaces to a safe level, typically achieving a 99.9% reduction. Disinfecting kills a broader spectrum of microorganisms, including bacteria, viruses, and fungi, offering a higher level of pathogen destruction.
Can disinfectants be used on all surfaces?
Not all disinfectants are suitable for every surface type. Always read product labels carefully to confirm safe usage and recommended surfaces. For delicate, porous, or electronic items, it’s best to test the disinfectant on a small, inconspicuous area first or use products specifically designed for those surfaces.
How often should I disinfect high-touch surfaces?
Ideally, disinfect high-touch surfaces daily, especially in households with vulnerable individuals or during illness outbreaks. In high-traffic public or work areas, more frequent disinfection may be necessary to maintain hygiene and reduce germ transmission.
Do I need to clean surfaces before disinfecting?
Yes. Cleaning surfaces beforehand removes dirt, dust, and organic material that can hinder the effectiveness of disinfectants. For optimal disinfection, always clean surfaces thoroughly before applying disinfectant products.
Are antibacterial wipes effective against viruses?
Many antibacterial wipes are formulated to kill bacteria and some viruses; however, effectiveness varies by product. To ensure antiviral efficacy, use wipes that are EPA-registered and explicitly state virucidal properties on the label. Follow manufacturer instructions for maximum effectiveness.
Additional FAQs
What is the safest way to use disinfectants around children and pets?
Keep disinfectants out of reach of children and pets. Use them in well-ventilated areas and ensure surfaces are dry before allowing contact. Opt for disinfectants labeled safe for households with children and pets whenever possible.
Can I use disinfectants on food-contact surfaces?
Disinfectants used on food-contact surfaces must be approved for such use and rinsed thoroughly with water after application to avoid contamination. Always follow guidelines for food-safe disinfecting.
How long do disinfectants need to remain wet on a surface to be effective?
Most disinfectants require a specific contact time, usually between 1 to 10 minutes, to effectively kill germs. Check product labels for recommended dwell times and ensure the surface remains visibly wet for that duration.
