440-R SMT Detergent is available in a ready-to-use spray bottle for safe, effective manual cleaning of SMT stencils and related tooling.  The stencil-cleaning chemistry  is verified for specific parameters of environmental safety, user safety and cleaning efficiency by the U.S. EPA’s Environmental Technology Verification Program. 
While ultrasonic technology is effective for removing solder paste from SMT stencils, manual cleaning continues to be common. Stencil cleaning has been identified as the most hazardous process with the greatest potential environmental impact associated with SMT assembly.  Flammable and VOC solvents such as alcohol and acetone are commonly used for manual cleaning and poisonous heavy metals such as lead often come in contact with the user.  This safe water-soluble detergent cleans effectively, improves print production and eliminates noxious odors and hazards associated with solvent cleaning.
