Cleaning is the process of removing unwanted soil from a surface and rendering it suitable for further use or processing. The type and composition of soil and surface must be determined in order to select the right cleaner. Next, the type of cleaning process must be known. Finally, the desired degree of surface cleanliness and it’s criteria must be understood. How clean must the surface be and how will that be measured?

Most cleaners displace and suspend or emulsify soils. Mechanical agitation accelerates this process. Alkaline cleaners are typically composed of alkaline salts, emulsifiers, wetting agents sequestering agents and inhibitors. Solvent based cleaners dissolve all or part of the soil.

The surface’s chemistry, reactivity, and complexity are the main factors to consider. The cleaner should be compatible with the surface under the conditions of operation. Most metal surfaces will be more susceptible to corrosion once they have been cleaned. This must be addressed by incorporating an inhibitor in the cleaner or applying one immediately after.

The composition and quantity of the soil are major factors in determining the proper cleaner and cleaning process. Soils may build up in the cleaner bath and affect performance. Soil load should be monitored and held below tolerance limits by treatment, or bath renewal. Solids can be controlled with proper filtration. Liquid soils can be removed with skimmers, coalescers or centrifuges if they are not overly emulsified or dissolved by the cleaner.

The chemical and physical process of cleaning needs time to be completed. Reducing the time places greater performance demands on the cleaner and/or the cleaning equipment.

Higher temperatures can reduce the viscosity of residues and increase cleaning efficiency. However, temperatures above those recommended for a given product may compromise performance and waste the cost of energy.

Water normally contains dissolved ions like sodium, calcium, chloride, and sulfate. These can be at high levels or can buildup over time through evaporation of the water. They can affect stability, corrosion, residues, rate of bacterial and fungal growth and the efficiency of the cleaner. Physical or chemical treatment of the water can remove or tie-up some of these ions.

There are two basic type of washers, spray and immersion. Spray washers can vary in the type, number, position and pressure of the spray heads. Immersion washers can vary from simple soak tanks to mechanically agitated, ultrasonic, or electrolytic units. Maintenance of the washer mechanisms, rinses, and blow-offs is critical.
