Liquid PBW is a buffered alkaline detergent that has been proven to be more than an effective substitute for caustic cleaners. Because of its unique formulation of buffers and mild alkalis, it is safe on soft metals such as stainless steel, aluminum, and on plastics. PBW uses active oxygen to penetrate carbon or protein soils and is not affected by hard water. The oxygen also helps in reducing B.O.D. and C.O.D. in wastewater, which is an added environmental benefit. The concentrations to remove these soils are typically in the 1% range. However, due to soil and water conditions this concentration will vary. To help in hard water areas PBW has been formulated with enough chelators to tolerate hard water over 17 grains. PBW. is an excellent choice as a soak cleaner because it does not require excessive heat as do most caustic based cleaners. This product has cleaned brass and copper filters, and industrial aluminum surfaces successfully.
