Abstract
A cleaning composition is particularly suited for cleaning dirty intake valves. The cleaning composition includes a high solvency surfactant/solvent which has a Kb greater than 100 or polar Hansen solubility parameter greater than 6. The surfactant/solvent is combined with an organic carrier and a surfactant. A wetting agent may also be employed. The cleaning composition is added to the intake air as a mist as the engine is running.
