We are using a �spray� type stencil cleaner and hot DI water to clean water washable solder paste. I want to use the stencil cleaner to also clean misprinted PCBs. However, we consistently find solder balls on side A of a double-sided misprint. We

Your flux residues may be acceptable for your drain, but the solder balls won't be. You'll need to filter and dispose of the filters per your local city, county, and state regs. Either that or just boil the water off and dispose of the dry remains wi
