Aqueous cleaning is mostly used in homes in washing machines for washing clothes, in dishwashers to wash dishes, or in geysers for body washing. Here, washing denotes using water, soap or detergent, some scrubbing, and even heat to boost the washing results. Industrial cleaning can be considered as an extended version of the above-mentioned cleaning types. It uses some advanced and sophisticated techniques for more consistent cleaning outputs. Industrial washing systems use agitation, heat, and water along with cleansing agents.
Choosing the chemical for aqueous cleaning is completely dependent on the chemical’s ability to clean and dissolve the soil. The selection of the cleaning equipment type relies on the material’s substrate and the total amount of soil that has to be removed from the material. The current market has aqueous cleaning chemicals suited to clean both non-ferrous and ferrous metals with more consistent and efficient cleaning results. The number of stages chosen for the cleaning equipment also varies depending on the amount and type of soil, equipment type, agitation, heat, substrate, etc.
The cleaning agents of aqueous cleaning have a complex nature as it involves different materials, coupling agents, surface active agents, sequestering agents, building agents, etc. Lube oil, loose burr, fingerprints, dust, petroleum grease, silicone grease, water-soluble oil, etc are the soils that use aqueous cleaning agents for cleaning.
Aqueous cleaning is a cleaning process combining a water-based cleaning solution’s chemical solvency with a kind of thermal/mechanical energy. With prior considerations on cost, safety, and environmental regulations, it has already been replaced and will be opted for in the coming years instead of solvent cleaning.
The aqueous cleaning process is considered to be more complex than the replacing solvent process. For example, a lot of vapor degreasers just take a single step for the wash/rinse/dry cleaning cycle. But in a water-based process, there will be three or more steps separately. To get the desired cleaning results, sometimes each of these stages in the cleaning has to be done multiple times. In washing, the parts will be exposed to a cleaning agent that removes the soil. The cleaning agents present in the parts will be removed through rinsing and the drying process finally dries all the water in the parts. But aqueous cleaning improves cleaning efficiency, cuts down operating charges, provides more efficient repeatability, reduces environmental control, and offers more process control.
Agitation gives better results to aqueous cleaning. It will also cut down the cleaning time. Other factors that can improve aqueous cleaning results are giving adequate time for the whole cleaning action to complete, the right quantity and concentration of the chosen chemical, and temperature. Mostly, they are referred to as TACT which stands for Temperature, Agitation, Chemical, and Temperature. The quality of water is also an important factor to deliver better results. Most people use deionized, demineralized water free of salts and minerals to get more accurate results without much residue left after cleaning. Each of these factors may vary depending on the cleansing operation you carry out.
