CAUTION: This microfiber brush cover is more aggressive than the other options. It can scratch delicate wheels especially painted black. This aggressive cover is paired with the red handle as a warning!!! Clean dirt and grime between spokes, into the barrels of your wheels and on other hard-to-reach areas with ease using our microfiber wheel brush. We've designed this wheel scrubber brush with a nylon brush cover to be strong, and aggressive.
