Bubble-Bandit markets products for both Dishwashers and Laundry, for people in hard-water areas who do not use a water softener, and have been disappointed with poor results, and mineral "scum" buildup in their machines as a result of the change to washing sodas.
With either of their products, they're certainly worth trying. However, I (like others) have absolutely no clue whether their products use enzymes, oxygen or chlorine bleaches, optical brighteners and other products intended to clean or "fake clean" your stuff...
Last I looked, I could not find the MSDS, and thus could not determine what was going into these products.
