Gator’s Jumbo Tire & Sidewall Brush is made to outlast the abuse experienced with automotive wheel cleaning and hold up to the chemicals that it is commonly used with. The bristles are set in a Plastic Foam hardened material that is capable of being left in a bucket full of your favorite Gator Detail Supply tire & wheel wash without causing damage to the brush head or bristles. The brush’s plastic foam body also helps to resist scratching your wheel’s finish.
