What Percent Isopropyl Alcohol Is Best?
Isopropyl alcohol, also known as rubbing alcohol, is a common household item that is widely used for cleaning and disinfecting purposes. It is an effective solution for killing germs, bacteria, and viruses on various surfaces. However, it is important to know what percentage of isopropyl alcohol is most effective for different uses.
The most common concentrations of isopropyl alcohol available in the market are 70%, 91%, and 99%. Each concentration has its own specific uses and benefits.
70% Isopropyl Alcohol: This concentration is the most widely used for general cleaning and disinfecting purposes. It is effective in killing most types of bacteria, viruses, and fungi.

91% Isopropyl Alcohol: This concentration has a higher percentage of alcohol and is more effective in killing bacteria and viruses. It evaporates quickly and leaves no residue, making it suitable for use on electronics, such as computer screens and keyboards, where moisture can be damaging.
99% Isopropyl Alcohol: This concentration is the most potent and powerful. It is highly effective in killing bacteria, viruses, and fungi. It evaporates quickly and leaves no residue, making it ideal for cleaning delicate electronics, such as lenses, camera sensors, and circuit boards. However, due to its high potency, it may not be as effective in killing certain types of bacteria compared to lower concentrations.
