Why does a brand new washing machine leave soap in clothes?
Modern washing machines and certain products like Castile soap can cause detergent buildup that standard wash and rinse cycles fail to flush out. This leaves clothes soapy even after replacing the machine, running extra rinses, and verifying that the plumbing is hooked up properly.
