Mi-Clean™ 24 is a high-strength, liquid concentrate composed of a blend of acid, solvent, surfactants and chelators designed to accomplish in one step, the cleaning and preparation of a variety of metal surfaces prior to blackening, phosphating and chromating. It will remove most oils, rust, heat-treat scale and shop soils efficiently and quickly. It is a good prepaint conditioner for steel and cleaner/etchant for aluminum with slow-controlled etching.
In contrast to highly alkaline cleaners, it is very free rinsing in water.
Mi-Clean™ 24 may be used in concentrations ranging from 5% to 50% by volume in water and temperatures from ambient to 140 F. The concentration, immersion time and temperature required will depend upon the degree of soil and surface oxidation. A 50% concentration is recommended with heavily rusted surfaces. A 5% concentration is recommended primarily for surface activation. Heating the solution will speed up the reaction and decrease the cleaning time.
Mi-Clean™ 24 can be contained in tanks made of stainless steel, lined steel, polypropylene, polyethylene, PVC or other acid-resistant materials.
Mi-Clean™ 24 concentrations may be maintained by simple periodic additions of concentrate or by a quick titration method, which is furnished upon request. It has a high tolerance for metals, soils and oils and does not pose a disposal problem.
