    Abstract: An aqueous cleaning fluid is provided for retarding electrolysis between dissimilar metals in an electrical circuit and removing contaminates and metal said from electrical conductors. This reduces resistance within the circuit and increases circuit efficiency. The fluid is a complex of naturally occurring essential oils mixed with a surfactant mixture to form a concentrated solution. The concentrated solution is diluted with distilled water and drying agents to levels suitable for application in field operations at or near a job site. The cleaning fluid is applied to conductors within a circuit with a spray bottle. The electrical circuit is taken off line, the conductor surfaces are exposed, and the conductor surfaces are wetted with cleaning fluid until some of the cleaning fluid drips from the conductor surface. Then the circuit is reassembled and the circuit is put on line.

    Abstract: The invention relates to non-ozone depleting cleaning compositions for degreasing elements in manufacturing and engineering processes like oily machine parts and for defluxing printed circuit boards, used in the electric and electrical industry. The composition according to the invention contains at least one C.sub.6-12 alkyllactate ester, preferably 2-ethyl hexyl lactate, in an amount of 70-99% by weight and at least one emulsifier, preferably n-octanol, in an amount of 1-30% by weight. One of the main advantages of the present cleaning composition is based on the fact that in the rinsing step with water for removing the cleaning composition from the treated surface an emulsion is formed, which on the one hand is stable enough for having proper rinsing ability and on the other hand--after the rinsing step--will separate rather quickly into an oil and a water phase. This last mentioned phenomenon provides the benefits of reusing the active cleaning agent, i.e. the C.sub.6-12 alkyllactate ester and reusing and/or partly discarding the waste water being toxicologically and environmentally safe.

    Abstract: A pre-moistened towelette wipes a compact disc clean without leaving a visible residue thereon. An ultra-pure tissue, free of binders, fillers and dyes, is permeated with a liquid cleaning preparation comprised of a highly concentrated solution of ultra-pure alcohol, a non-ionic, ultra-pure surfactant, and ultra-pure water.
