FREIBONE “ACID CLEANER” AC20 is a Liquid Mineral Acid Cleaner, with a special blend of surfactants designed to remove soap lube, Drawing oil, zinc phosphate and oxidation stains from the aluminum surface with very little attack on the aluminum. The cleaning action softens hard-to-remove soils and the acid helps lift the soil from the surface. Mechanical impingement will also aid in removal of the soil by hydraulic action. The mechanical scrubbing can be in the cleaner tank or a subsequent rinse. The cleaner will not emulsify the soils so the surface of the tank should be skimmed clean to avoid re-deposition. If a spray is used the sump should be skimmed and filtered clean to avoid clogging the spray nozzles. The resulting surface will be active (deoxidized) and clean.

Recommended tank material is the same for a sulfuric acid pickle. Coroseal lined or plastic lined tank. The cleaner will slowly etch stainless especially when aluminum is gassing in the tank. Soak or spray with AC20 followed by an agitated immersion and /or spray rinse.

The usual build-up concentration is 10-30% by volume added into 90-70% by volume water.

Cleaning times vary from 1 to 5 minutes depending on soil and the time the part takes to acquire the operating temperature (range of 150-170°F). Cleaning times should be kept to a minimum to maximize bath life. Temperature of operation depends on the softening temperature of the soils.

Follow the Cleaning station with counter flowing rinse and/or a good impinging spray.

Free Acidity = 22.4 points = 20% bath or FA points x 0.87 = % Active Freiclean AC20 The ratio TA/FA = 1.23 for a new bath.

Aluminum Content is at a maximum at about 1/3# / gallon or when the TA/FA= 1.69 A partial bath make-up can restore some of the performance of the bath.

Waste treatment: Follow normal procedures to remove aluminum from an acid solution. Follow local regulations for disposal or reclamation.
