Aircraft cleaning is a major contri

Aircraft cleaning is a major contributor of hazardous waste generated at aviation maintenance
facilities. To reduce the amount of hazardous waste generated at these facilities, new concepts,
materials and processes need to be explored. Different cleaning methods and cleaners should be
substituted into current cleaning processes. These methods could range from manually wiping or
squeegeeing a part to substituting a mechanical cleaning method for a solvent or chemical cleaner.
Cleaning methods could also include material substitutions such as using aqueous and terpene
cleaners in place of chemical or chlorinated solvents. It is important to note that all cleaning
processes should first use the least hazardous cleaning agents and methods to minimize waste.
