Cleaning technology is ....

the synergy of the chemical and mechanical knowledge, where the chemical one interfaces with the contaminant and the mechanical one with the part.... Cleaning is always a chemical-physical action based on factors interacting with each other to obtain the result.....  All this, integrated with the knowledge of the contaminants and the processes that generate them, is called "know-how"......A cleaning problem has never one solution only, even though only one is the best for a specific application...
