I am suggesting that an investigation is launched into the possibility of contract aircraft cleaners unknowingly scratching aircraft windshields while performing their duties. After thinking more about the Tech Ops Update and a recent CBT (Computer Based Training) on 737 Windshield scratching I wonder if the uptick in B737 windshield replacements is from non-certificated individuals inadvertently imposing damage to the windshields. I am not sure what method the cleaners use; what cleaning agents; what type of cloth; etc. Do the materials conform to the Boeing Maintenance Manual? Not pointing a finger here; but just thinking that we may have an opportunity to reduce inadvertent damage to the windshields here if we initiate a change management process. Again; the cleaners are just doing what they believe is their job; but it may have been an oversight that we (company) requested them to clean the windshields; or didn't realize that they were cleaning the aircraft windshields; potentially using a damaging process; chemical or consumable item (rags; paper towels; etc.).
Aircraft Technician suggests a link between aircraft cleaning and windshield damage.
