This acid-free wheel, tire, and brake cleaner is safe for all finishes—steel, aluminum, chrome, paint, and more. Tough on brake dust, iron, and road grime, yet gentle on rims. Restores wheels and tires to a factory-fresh look. Spray on, agitate with a soft brush, rinse, and wipe clean. Use straight or dilute in a foam sprayer for thick foam that lifts dirt easily. Leaves a protective coating that repels future grime and allows for easy sealant application to keep wheels cleaner longer.
