The bristles of the bore brush are typically made from materials that can withstand the pressure and friction created during the cleaning process while being stiff enough to reach into the grooves of the rifling.

Using a cleaning rod provides the necessary leverage and control to properly maneuver the bore brush through the length of the barrel, ensuring a thorough cleaning. This process is essential for maintaining the accuracy and function of the rifle, as fouling buildup can affect the rifle's performance over time.

Other methods, such as compressed air, vacuum, cloth, toothbrush, sponge, or soap solution, may assist in cleaning other components of the rifle but are not specifically designed to clean the barrel effectively. Compressed air can remove loose debris but may not engage the stubborn fouling as effectively as a bore brush can, while cloths and toothbrushes lack the rigid form necessary to reach and clean areas inside the barrel properly.
