The soft, dense carpet fibres of the Wheel Woolies® are 100% polypropylene and chemical resistant. These fibres are great for holding in suds to transfer them to the wheel. Wheel Woolies not only perform an excellent job of cleaning the outside surfaces of the wheel but also allow the user to get into the small holes and crevices where the brake dust collects.

There's no metal in these brushes and the flexible handle is smooth as to not cause scratches unlike the twisted wire spoke brushes which can really scratch up a wheel if used carelessly and splatter you with wheel cleaning chemicals and dirty water. The synthetic fibres of wheel woolies are chemical resistant so they won't fall apart like cheaper imitations. 

The larger 18" Brush is ideal to reach the inner rims to remove break dust. Made in the USA.
