We sought to investigate the effects of professional and household dishwashers
Interestingly, detergent residue from professional dishwashers demonstrated the remnant of a significant amount of cytotoxic and epithelial barrier–damaging rinse aid remaining on washed and ready-to-use dishware.
Is the reader to draw the conclusion that significant levels of rinse-aid are not found in dishes cleaned by home dishwashers?
A professional dishwasher completes 1 or 2 wash and rinse cycles using 3.5 L of water per cycle.
That's about 1/4 the water usage of a home dishwasher. Does an increased amount of water in home dishwashers result in negligible levels of rinse-aid?
As I mentioned in another comment, the easy way to test for this is to take a freshly-dishwashed glass and fill it with water. Look for foamy bubbles that don't clear up quickly around the edge. Then rinse it thoroughly and try again.
With most home dishwashers, I have seen evidence of leftovers.
