Cascade Ran Commercials
When their enzyme based (along with oxygen bleach), deterents hit the market showing housewives pulling faces, waving their hands in front of their noses and other depictions showing "disgust" with the heavy chlorine bleach scent from standard dw detergents. The appeal of new formula was an end to the dreaded bleach smell.
Many persons with breathing problems and or for other reasons cannot deal with chlorine bleach fumes, and often running a dishwasher meant not only filling the kitchen, but depending upon the layout of the home, an entire area with the smell of bleach. Many housewives waited until the last thing at night to run the dw(amoung other reasons), to start the dishwasher because at least the household would be upstairs or otherwise away from the wafting scent of bleach.
Myself never could stand the heavy scent of some chlorine based dw detergents. And as above, always ran the unit late at night when one was out of the kitchen area to escape that horrid smell.
Oh yes, not to mention the powerful bleach smell if one opened the dishwasher mid-cycle (to add an errant item), and all that hot bleach laden water/steam came gushing out.
Commercial dishwashers by and large do not run nearly long enough for enzyme based dishwasher detergents to really get going. Plus chlorine bleach (if the product is approved) in a detergent satisfies the "chemical sanitiation" part of most codes regarding using automatic dishwashers.
Chlorine bleach is cheap and common enough, which is why one most always finds it being used in restaurants and other places that serve the public. From dishwashing to the "rag" used to wipe down tables between servings, all one smells is bleach, bleach, bleach.
