Which method is best for cleaning leads?

The most effective method for cleaning leads, especially in a clinical or sleep study setting, involves the use of isopropyl alcohol. Isopropyl alcohol is an excellent choice because it not only sanitizes but also effectively removes oils and residues that accumulate on the leads. This ensures optimal conductivity and helps to prevent skin irritation during the sleep study.

Using soap and water may not provide sufficient disinfection or residue removal, while bleach can be harsh and potentially damaging to the leads and electrodes due to its corrosive nature. Distilled water may clean some surface dirt but does not have disinfectant properties and is unlikely to eliminate oils or contaminants effectively.

In summary, isopropyl alcohol is the superior option for maintaining the integrity and functionality of leads used in polysomnographic studies.
