When cleaning electrical instruments, which method is not recommended?

Using vigorous scrubbing to clean electrical instruments is not recommended because this method can damage sensitive components, protective coatings, or delicate parts. Electrical instruments often have intricate designs that require gentle handling. Aggressive cleaning techniques can lead to abrasion or breakage, compromising the integrity and functionality of the instrument.

In contrast, using compressed air is effective for removing dust and debris without direct contact, while a soft cloth is ideal for wiping surfaces without causing scratches. Approved solvents are also designed to clean effectively without harming the instrument, as they are formulated to dissolve contaminants without negatively impacting the materials from which the instruments are made. Therefore, employing gentle and appropriate cleaning methods is essential for maintaining the longevity and performance of electrical instruments.
