These brushes were designed for reaching between spokes and around rims to remove baked on brake dust, caked on road grime, grease, oil and anything else that wheels collect from the road. Without the proper tools, wheel care is a bear. These cone-shaped brushes easily address the intricacies of all models and sizes of wheels and spokes, no matter how uniquely shaped, making upkeep easier than ever. Appropriate tools greatly reduce the time it takes to tackle any job. Don't wrestle with the wrong brush or clothit will only frustrate you! Your results will be much more satisfying when you utilize a tool that's made for the task. These wheel brushes have stiff, yet non-scratching bristles to remove offensive dirt and grime. When choosing a wheel cleaning product, keep in mind that today's best products are powerful, yet environmentally safe. I recommend DP Gel Wheel Cleaner for a harmless but potent product. Some companies are manufacturing double-duty products that effectively and safely dissolve dirt and grime on both wheel and tires, eliminating the necessity of purchasing separate products. Wolfgang Tire & Wheel Cleaner is a great choice if you wish to go that route.
