Quench-Kleen 5343 is a low-residue alkaline spray cleaner specifically formulated for heat-treating applications. It presents no barrier to subsequent coating processes or welding, and it is proven to be a safe and cost-effective alternative to solvent emulsion cleaners. Quench-Kleen 5343 is ideal for removing shop soils such as quenching oils, soluble coolant cutting oils and metal-forming compounds. The cleaner excels at removing quench oils by splitting them out of metalworking solution in single- or multi-stage washing equipment. It is also effective in spray washers with high-pressure nozzles operating at pressures of 40-250 psi. Users can clean surfaces as warm as 170°F with no harmful effects to work staff or the environment.
