Blaster Non-Chlorinated Brake Cleaner is the best defense against squeaky brakes and brake squeal. The brake parts cleaner quickly dissolves and flushes away brake fluid, oil, grease and other surface contaminants. Its fast, evaporating formula leaves no residue and improves overall brake performance. Spray directly on rotors, gasket surfaces, drums and brake linings to prevent rusty rotors or other damage caused by contaminants and brake dust. Simply hold the can 1-2 feet from the surface, start by spraying at the top and move downward to clean dust, dirt and other contaminants away from the brake parts. For best results, remove vehicle wheel first and spray directly on the exposed brakes components. Securely replace wheel when finished. Stubborn dirt sticking around. Another spray should do the trick.
