What must be done to electrical equipment before cleaning it?

Before cleaning electrical equipment, it is essential to disconnect it from the power source. This step is critical for ensuring safety, as it eliminates the risk of electric shock, short circuits, or unintentional activation of the equipment during the cleaning process. Being disconnected from the power source also safeguards the equipment itself from potential damage caused by cleaning solutions or moisture.

While drying off equipment, covering it, or removing batteries might be relevant steps in certain contexts, they do not address the immediate safety concerns that arise from electrical hazards. Properly disconnecting the equipment provides the first line of defense against accidents, making it a fundamental practice in both residential and commercial settings.
