Ideal for cleaning complex wheel designs where access between spokes and to the inner rim itself is severely restricted. Despite the generous diameter of the brushes, the soft Nylex bristles are highly flexible, meaning that the brushes are able to access extremely narrow gaps safely and effectively. The Nylex bristles are also chemically resistant and feature a memory design, meaning that the shape of the brushes can be restored at any point by gentle heating with a heat gun. The main shaft of each EZ Detail Wheel Brush is highly flexible, and can be safely bent to any angle to afford greater access to inner rim surfaces. The tip of the shaft is covered in vinyl to prevent any accidental scratching, and a rubber knuckle guard sits atop the ergonomically-shaped handle in order to protect your hands as you reach into the backs of deep-dish wheel designs.
