The type of aircraft skin, whether composite or aluminum, significantly influences the choice of cleaning agents used during Ground Support Equipment (GSE) maintenance due to the different chemical sensitivities of these materials. Aluminum is susceptible to corrosion, particularly from alkaline or acidic cleaners. Strong alkaline cleaners can etch the aluminum surface, causing pitting and weakening the metal. Similarly, acidic cleaners can dissolve the aluminum oxide layer that protects the metal from further corrosion. Therefore, when cleaning GSE that comes into contact with aluminum aircraf....
