Solvent degreasing is a process used to prepare a part for further operations such as electroplating or painting. Typically it uses petroleum , chlorine , dry ice or alcohol based solvents to dissolve the machining fluids and other contaminants that might be on the part.
One such process, electroplating, is particularly sensitive to part cleanliness, as even thin layers of oil can hinder coating adhesion. Cleaning methods encompass solvent cleaning, hot alkaline detergent cleaning, electro-cleaning, and acid etch. In industrial settings, the water-break test is a common practice to assess machinery cleanliness.
Conservation-restoration is the practice of cleaning and discovering the original state of an object, investigating the proper treatments and applying those treatments to restore the object to its original state without permanently altering the object, and then preserving the object to prevent further deterioration for generations to come (Caple, p. 5-6).

The typical bell applicator consists of five major assemblies: the valve module, the bell cup, the turbine, the shaping air shroud, and the electrostatic system.. The valve module is a manifold consisting of passages for paint, solvent, and compressed air, and valves to control the flow of materials for paint delivery, cleaning and purging with solvent or hydropurge, and management of ...
Wash bottles may be filled with a range of common laboratory solvents and reagents, according to the work to be undertaken. These include deionized water, detergent solutions and rinse solvents such as acetone, isopropanol or ethanol. In biological labs it is common to keep sodium hypochlorite solution in a wash bottle to disinfect unneeded ...
Most glass cleaners are available as sprays or liquid. They are sprayed directly onto windows, mirrors and other glass surfaces or applied on with a soft cloth and rubbed off using a soft, lint-free duster. A glass cloth ideal for the purpose and soft water to which some methylated spirit or vinegar is added which is an inexpensive glass cleaner.
Provided the RCA clean is performed with high-purity chemicals and clean glassware, it results in a very clean wafer surface while the wafer is still submersed in water. The rinsing and drying steps must be performed correctly (e.g., with flowing water) since the surface can be easily recontaminated by organics and particulates floating on the ...
Self-cleaning glass is a specific type of glass with a surface that keeps itself free of dirt and grime. The field of self-cleaning coatings on glass is divided into two categories: hydrophobic and hydrophilic. These two types of coating both clean themselves through the action of water, the former by rolling droplets and the latter by sheeting ...
