I do not take very seriously recomendations from a site which advocates wasting all of the sugar in Tang to clean a dishwasher. Sugar is a precious, costly commodity that has always involved oppression and, even in modern times, near slavery in its production. Today, the Cuban families that own sugar plantations and run Florida politics are responsible for most of the pollution in the Everglades caused by fertilizer runoff. If you are not aware of this situation, read almost anything by Carl Hiaasen on the state of things in South Florida. These sugar owners are responsible for legislation ON A NATIONAL LEVEL which boosts the price of sugar so much that candy manufacturers have left this country for places where the world price of sugar is lower than our artificially high price, taking jobs with them. Because of their great wealth, they buy the votes of lawmakers, nothin new here, but another way the money in politics ruins politics and our nation. The import quotas for sugar are always a stumbling block in our dealing with Central and South American countries over trade. I read about one agreeement that permitted imported sugar to only be used in the production of ethanol, another boondoggle that was a gift to corn producers.
Plain citric acid works and is the principal active chemical in Tang. Citric acid can be found in most supermarkets in the canning supplies section. If you can't find it ask. If you can't find citric acid, white vinegar works also. Our 1959 GE Modile Maid's owner's manual had instructions for using it.
