The California Car Duster is a dust brush that attracts and traps dust and dirt like a magnet. Treated with an extra-firm wax coating on its cotton fibres, it prevents dust from settling back onto a car’s bodywork. Thanks to this special wax coating, the brush actually performs better the dirtier it gets. Washing the fibres may affect this coating and reduce its ability to attract and trap dust and dirt. The brush consists of soft fibres, ensuring a safe and scratch-free use on the most delicate surfaces.
