Ultrasonic Cleaning involves using high-frequency sound waves to remove contaminants from parts that have been immersed in a special cleaning solution.Effective cleaning of components is an integral part of reconditioning cylinders heads or other engine parts. Ultrasonic cleaning offers a quicker more effective and less damaging alternative to traditional sand blasting. The residue from bead blasting is also eliminated and therefore the potential for damage of the cylinder head once reassembled is totally eliminated.Cylinder heads have many blind passages and oil galleys that make them difficult to reach for cleaning by hand, Ultrasonic cleaning can reach those hidden areas that would not usually be accessible.
