Using a stiff brush to remove hair particles from clipper blades is an effective method for maintaining tool hygiene and functionality. A stiff brush is designed to dislodge and lift hair and debris from hard-to-reach areas within the clipper blades that may accumulate during use. This is important because clogged blades can lead to reduced performance, uneven cutting, and may also harbor bacteria or fungi, which could pose a risk to clients.

When compared to the other options, a stiff brush provides a thorough cleaning solution that is both efficient and safe for the intricate mechanisms of clipper blades. Compressed air, while effective in some scenarios, might not remove all hair particles and could potentially blow debris further into crevices. A cloth may also be useful for cleaning but does not have the same ability to penetrate the tight spaces between the blades. Relying on fingers can be less effective and presents the risk of injury from the sharp edges of the blades.

In summary, a stiff brush is the best choice for ensuring that clipper blades are properly maintained and free of hair, enhancing both their performance and lifespan.
