Isopropyl alcohol is widely recognized as the most effective substance for cleaning electrodes and leads due to its superior ability to remove oils, dirt, and other contaminants from surfaces. The alcohol evaporates quickly, which is crucial in a clinical setting, as it minimizes downtime between patients and prevents moisture from interfering with the electrical properties of the electrodes. Additionally, isopropyl alcohol has antiseptic properties, helping to reduce the risk of infection when applied to skin or equipment in contact with patients.

While other cleaning agents like bleach, soap and water, and hydrogen peroxide have their uses, they may not be as suitable for this specific purpose. Bleach can be too harsh and might damage the delicate components of electrodes or leads. Soap and water may not completely eliminate all oils, and moisture can lead to inaccurate signal recordings. Hydrogen peroxide, while useful for disinfection, may also leave residues or require rinsing that could be impractical in a fast-paced environment. Thus, isopropyl alcohol stands out for its balance of cleaning effectiveness, speed of drying, and safety.
