This cleaner will remove dirt and oil from the tire surface and is used to prep the sidewall for a tire lettering installation. Simply spray onto tire and thoroughly wipe down until all dirt and oil has been removed from the surface. Once the tire surface has been cleaned, you can install your tire lettering. While this is an alternative to using Acetone, maintain caution around wheels, chrome and other painted parts when spraying. If excess cleaner has dripped on rims or other components, simply rinse off with water.
