Ultrasonic Cleaner are very important to help our engineer clean motherboard with severe liquid ingress. They are specially developed to use ultrasound with the correct solvent cleaner to clean delicate items, like you laptop motherboard. Unlike alot of other repairers scrubbing a board with a brush and solvent cleaner can lead to damage to the motherboard.
Therefore we opted to buy two industrial sized ultrasonic cleaners and developed a custom made solvent cleaner.
Again only the best for your laptop.
