Wheel Brite is a highly concentrated formulated NON-ACID cleaner for use as a brake dust remover, road grime, dirt, and grease. For most applications mix Wheel Brite Concentrate 1 part to 4 parts water. For heavy cleaning dilute less if needed. Spray directly onto a cool Wheel Surface allowing 30 seconds to dwell without drying out. Scrub with a soft brush until Wheel Brite works into a foam. Rinse heavily with a strong stream of water as well as all surrounding surfaces. Do not use in direct sunlight as this may cause Wheel Brite to dry on the wheel. Wheel Brite Ready to Use is mixed at a 1:4 ratio.
