This wheel brush is very flexible and covered with vinyl to prevent unintentional scratches. A rubber protection ring sits on top of the ergonomically shaped handle to protect your hands as you go deeper into the rim. Despite the diameter of the brushes, the soft Nylex hairs are very flexible, which means that the brushes are able to clean very narrow gaps safely and effectively. The Nylex hairs are also chemically resistant and have a "memory", which means that the shape of the brushes can be restored by gently heating them with a hair dryer.
