Water should be used to clean water-based paints from the paint passing parts of the paint gun, and thinner should be applied to clean solvent-based paints. The holes of the air cap at the tip of the gun should be placed in thinner and then cleaned with air. No objects should be inserted into the holes of the air cap. The entire gun should be immersed in solvent for cleaning. If the entire gun is inserted into the thinner, it may damage the sealing equipment and cause the gun to leak air.
