No disinfectant is capable of killing all germs found on a hard surface. The absence of all germs is referred to as sterilization and is a process that surpasses the efficacy level achieved with any disinfectant solution. EPA-registered chemical sterilants are the only types of sanitation products that can make a claim to kill all pathogens on hard surfaces. Before deciding on which disinfectant is right for your specific purpose, be sure to read its label.
Many excellent disinfectant solutions exist that meet the needs of most applications. When choosing, consider a few key decision-making guidelines:. Surfaces to be disinfected: Some disinfectants are not recommended for all surfaces. One example is bleach, which can be damaging to stainless steel. Another is products with a high pH, which can damage floor finishes and fabrics. Neutral pH solutions are better on floors than high pH solutions, however they may not have all of your required kill claims.
Safety and user exposure: Building occupants, students, patients, residents, and janitorial staff may have skin or odor sensitivities to various disinfectant solutions. Dilution: Disinfectants come in concentrated, ready to use, wipes, and even aerosol forms, each with different kill claims. We think not much. The bottom line is that no matter what the marketing claim, no single disinfectant solution will work for every application and in every setting.

A more ideal solution is to use soap, but this brings another problem. Since commercial soap normally does not contain alcohol unlike soaps in the hospitals, rather than destroying oil particles and their associated germs , soap molecules work by dissolving the oil with water which is then washed away.
Therefore, its efficacy in killing germs is always been debatable. Image by Irina Ba on Unsplash. Most soap manufacturers advertise their product capable of killing So the next logical question would be, how reliable are their lab results? Generally, their lab tests and results are trustworthy, but there is a big pitfall that not many people know.
Their test procedures typically consist of placing germs on a surface, wiping that surface with the soap, and then finally the remainder of the germs are analyzed. The pitfall arises because their test conditions are different from our messy everyday life. Obviously, the inside of a laboratory is much cleaner than the outside world, so the results may not be true in every condition.
This indicates that washing hands with soap still does not leave germs to 0. One important thing to note is that soap is not really killing the germs in our hands, but rather washing them away. In a scenario where a soap really removes But when we are talking about the number of germs, we should be considering millions of them which is why it could still be dangerous.
