Directions for Use

Engine cleaning: With the engine off and cool, check for exposed or frayed wires. Cover air intake, electrical contact points, and carburetors, then liberally spray onto soiled areas. Let formula soak for up to 5 minutes, then wipe or brush away grime and deposits. Spray with water, careful not to soak electrical points. Leave surface to drip-dry excess water, and remove any covers shielding air intake. Idle engine for 15 minutes.

Tool cleaning: Liberally spray on soiled tools. Let formula soak for up to 5 minutes, and then wipe away grime and deposits with paper towels.
