Two Metal-Cleaning Solutions

Madison Chemical’s phosphate-free Aluma-Cling Blue eliminates having to brush by hand to clean bright aluminum and stainless steel. Clean-Gard 83 is an alkaline detergent that produces low-to-moderate foam, making it ideal for cleaning via ultrasonic cavitation.

Use Madison Chemical’s Aluma-Cling Blue at full strength at room temperature and follow with a cold-water rinse. Contact time depends on soil loading and application, but 1 min to 15 min is a reasonable starting point. Do a high-pressure cold-water rinse for optimum results on bright aluminum.

For immersion applications, Clean-Gard 83 is diluted to 3% to 10% by volume in water and used at 120 degrees F to 160 degrees F. Heavier soils and/or ultrasonic applications may benefit from temperatures up to 190 degrees F. Cleaning may be followed with an ambient-to-warm water rinse. Don’t rinse if rust protection is desired. For recirculated spray washers, use at 2% to 10% by volume in water from 130 degrees F to 160 degrees F up to 25 psi maximum.

Madison Chemical (Madison, IN) introduces two cleaning solutions.

Applied at full strength by pump or spray, phosphate-free Aluma-Cling Blue reduces the number of steps and often the manual brushing necessary to obtain a bright surface on 5000 and 6000 series aluminum alloys and stainless steel. The moderately acidic, thickened gel removes plasma smoke residue, weld marks, light oxide, and discoloration due to previous processing; and eliminates or greatly reduces streaking, yellowing, whitening, and over-etching caused by aggressive acids.

Designed for removing aged, oxidized, burned-on oil, removing grease, and other difficult cleaning operations, Clean-Gard 83 alkaline detergent is intended for immersion application, including ultrasonic and agi-lift, as well as recirculation spray washers up to 25 psi.

The formulation produces low-to-moderate foam, maximizing ultrasonic cavitation. When not rinsed, the cleaning solution offers very good rust protection. It’s ideal for use with ferrous, aluminum, and zinc alloys when used as directed, making it ideal for a wide range of manufacturing environments.
