Remember tincture of iodine? Detergent with Phosphates ? Model airplane glue with acetone ? Carbon Tetrachloride ? Darvons ?

It is perfectly legal to buy the phosphate and add it to your dishwasher or laundry. And it does make a difference.
Here is where I buy it:

PS: The dirty little secret the EnviroTards won't talk about is that this is not the kind of phosphate that causes environmental problems like eutrophication. But the facts be damned.
