While hydrogen peroxide has some disinfectant and sanitizing properties, it may not be the “world’s safest sanitizer,” as other disinfectants and sanitizers may also be safe and effective when used properly. Hydrogen peroxide has been found to have some antibacterial, antiviral, and antifungal properties, but its effectiveness in treating illnesses may vary, and it is not considered a cure for cancer. It is important to note that the use of hydrogen peroxide for medical purposes should be done under the guidance of a healthcare professional, as improper use can lead to adverse effects.
