What is the most commonly used antiseptic?

Alcohol
Iodine
Chlorhexidine
Hydrogen Peroxide

The correct answer is: Alcohol

Alcohol is the most commonly used antiseptic in various medical and dental settings. It is effective against a broad spectrum of microorganisms, including bacteria and viruses. Alcohol is widely used for skin preparation before medical procedures, as well as for disinfecting surfaces and instruments. Its fast-acting nature and broad antimicrobial activity make it a popular choice for antiseptic purposes. Iodine, Chlorhexidine, and Hydrogen Peroxide are also commonly used antiseptics, but alcohol stands out as the most commonly used due to its efficacy, rapid action, and broad spectrum antimicrobial properties.
