About AquaKlean® EF53

AquaKlean® EF53 is a mildly alkaline, multi-metal cleaner engineered for demanding industrial and aerospace cleaning applications. Its non-silicated, non-caustic chemistry removes oils, grease, fingerprints, inks, metalworking fluids, drawing compounds, and polishing and buffing residues while providing clean rinsing and reduced process residues.

Built-in flash-rust inhibition helps protect ferrous surfaces during processing, while an oil-splitting formulation supports efficient operation in recirculating cleaning systems. AquaKlean® EF53 is suitable for ferrous metals and aluminum, with cuprous alloys requiring application testing for potential discoloration.

AquaKlean® EF53 meets MIL-PRF-85704C Type II and can be used in spray, tank and solvent-replacement cleaning operations. Its combination of mild alkalinity, low-to-moderate foam, zero VOC and metal protection makes it particularly useful where controlled cleaning performance and substrate protection are both critical.
