Emulsion Cleaning Process

Emulsion cleaners leave an oil-like residue on parts, and very often this is unacceptable to the next process, or the appearance is unacceptable if cleaning is the final process. The emulsion is usually followed with an alkaline detergent wash to remove the last traces of contaminants. Then a plain or deionized water rinse may be required to remove the alkaline. If parts must come out of the system dry, then an ambient or heated air drier must be included. Thus, many emulsion cleaning systems have four stages, which will be discussed below.
