My dishwasher is the Bosch SHE58Cóan amazing machine. Stainless-steel front, concealed controls, six cycles to choose from. The manual runs a brisk 63 pages.

Best of all, it prevents the washed-away grime and minerals from gumming up the inner-workings of your dishwasher. Traditionally, phosphorus was loaded into dish detergent in the form of phosphates, which are compounds of phosphorus bonded to oxygen. (PO4 if youíre keeping score at home.) Prior to last July, most detergents were around 8 percent elemental phosphorus. Now theyíre less than 0.5 percent phosphorus. ...
