There are sodium citrate compounds that are an effective replacement for phosphorus. Tests have been conducted and the results were published in a number of Quebec and Canadian journals in recent months. Some of these products were considered to be as effective as detergents containing phosphorus. However, in terms of my own experience, I have yet to see anything as efficient and effective as phosphorus. But, perhaps we have to make Canadians understand that they cannot have a perfect dishwashing detergent that leaves no traces on their dishes—by that I mean chemical traces—and that at the same time does not harm the environment. So, we have to choose: are we going to make the environment pay or can we get along with glasses that may have small water spots on them after drying? I think it's up to Canadians to decide.
