Since the beginning of the industrial revolution, the need to clean the machines has posed a challenge. The solvents that are effective at cleaning parts have negative impact on the people who use them and once they’re used, create damage to the environment. As industrial processing expanded through the 20th century the problem of industrial solvents became more and more serious. The impact on both workers health and the environment became obvious. The need for alternative safe and environmentally friendly cleaning methods became more urgent.

This search led to the use of water as the primary solvent, along with carefully chosen chemicals for industrial cleaning of parts. Combinations of detergents, emulsifiers, PH buffers, chelating agents, deflocculants, inhibitors, and anti-foaming agents are formulated to provide necessary cleaning based on the substances to be removed. In most instances, simply soaking a part does not provide fully effective cleaning, so sprayers are used to add pressure to the effect in varying degrees. Heat, ultrasound and agitation can be added to increase the effect.

While aqueous cleaning produces waste, it is far safer for both the people who employ it and for the environment. Additionally, processing options exist to reduce even further the adverse impact of the waste products. Effective and safe, aqueous cleaning requires careful consideration of the items to be cleaned, the contaminants, the degree of cleaning required, and the subsequent disposal of the resulting waste products.
