Oxide Remover (OR) Cleaner

EMS Catalog #71052, 71053

Applications and Use

Electron Microscopy Sciences' Oxide Remover is a blend of detergents in an acidic carrier which is phosphate-free and biodegradable. This formulation has been developed to rapidly remove ruse and oxides from many metals. It is used in cleaning and reconditioning relay and switch contacts, removing oxides that result from assembly operations utilizing soldering, brazing, or welding, and similar applications. It can also be effective on ferrous materials for removing surface oxides resulting from storage. Although the solution may etch or attack reactive metals, it is especially effective with stainless steel, copper, and tin components.

Application Procedures

Electron Microscopy Sciences' Oxide Remover solution is readily mixed in a concentration of 6-7% by volume, and can be used at solution temperature of up to 120°F (48°C) in cleaning tanks. Optimum performance will be realized at this slightly elevated solution temperature. Cleaning tanks, heating coils and related components should be fabricated from stainless steel or other materials capable of withstanding acidic solutions. For optimum cleaning, Electron Microscopy Sciences' Oxide Remover should be operated at recommended temperatures. Cleaning time is dictated by the quantity and nature of the soil. Operating below the recommended concentrations, temperatures, or time will generally result in poor cleaner performance, characterized by cloudiness and water breaks. Operating above the recommended parameters may lead to component metal attack or cause the surfactants to separate from the solution causing poor cleaning. It is imperative that the solution be allowed to "degas" at operating temperature for a minimum of 10 minutes prior to placing the parts into the cleaning solution. It is best if ultrasonic energy is applied during this time to enhance degassing. Thorough rinsing is suggested for removal of cleaning solution. As with any process involving water, drying should be considered as the final step. The selection and use of the proper ultrasonic cleaning equipment and component fixturing will influence the cleaning efficiency and performance of Electron Microscopy Sciences' Oxide Remover.
