Oakite® Aluminum Cleaner 164
Inhibited alkaline compound for cleaning aluminum by tank immersion.
A Product of Chemetall US, Inc.
PRIMARY APPLICATION
Oakite Aluminum Cleaner 164 is an inhibited alkaline compound containing silicates. It’s for heavy duty tank cleaning of aluminum castings, forgings, extrusions, etc., and for cleaning aluminum sheet prior to anodizing, deoxidizing and prepaint treatments.
Besides aluminum, the detergent can be used for cleaning steel, stainless steel, copper, zinc, brass and aluminum.
The specially formulated material removes a variety of identification inks as well as shop soils like grease and oil. It is also used for cleaning aluminum equipment in food plants, oil refineries, chemical plants and other industries. With controlled foaming, Aluminum Cleaner 164 is suitable for use in air agitated tanks. It rinses freely.
Oakite Aluminum Cleaner 164 is also authorized by the USDA for use in federally inspected meat and poultry plants.

APPLlCATlON PROCEDURE
Add the total required quantity of Oakite Aluminum Cleaner 164 to half the volume of water, cold, while stirring and heat to about 82°C (1 80°F). Then, add the remaining half of water and adjust solution to operating temperature.
Oakite Aluminum Cleaner 164 is normally used at a 45 to 75 g/L (6 to 10 oz/gal) of water and in the temperature range of 49° to 82°C (120° to 180°F). It may be used in air-agitated tanks without foaming excessively.
Solution Control: Concentrations are titrated using Gardotest Procedure 92 or Gardotest Procedure 123.
For concentrations use Gardotest Procedure 92.
Sample Size: 25 mls Factor: 1.0
For free or total alkali use Gardotest Procedure 123. (See Procedure)
EQUIPMENT
The Chemetall Oakite Electrodeless Conductivity/Concentration Control System and Chemical Metering Pump can be used to monitor and automatically maintain the concentration of this product using conductivity.
