The Heavy-Duty Speedy Drill Brush is meant for intense scrubbing.
It lifts and easily removes dirt, grease and grime from tires and pick-up truck bed liners.
Also cleans and scrubs dirty rubber mats and cargo liners.
These bristles are stiff enough to clean white walls and white lettered tires.
This brush can also be used on tile and grout in bathrooms and showers.
