From the tightest and smallest of areas to the hardest to reach crevices, this brush removes dust, dirt, crumbs and gunk. Soft customer designed gentle bristles reach between small areas to lift and remove particles. This brush can even remove wax and polish residue - especially around emblems, molding, trim, door handles and more.
