From a short distance, apply evenly to a cool, dry wheel surface and let sit for 3-5 minutes. The liquid changes its color to red as it reacts with the iron particles of the brake dust. In case of extremely stubborn soil, use a sponge or soft brush to gently agitate. Finally, rinse thoroughly using a string water jet or high-pressure washer.
Please note: Protect against freezing. So not apply in direct sunlight or to hot wheels. Do not allow to dry.
