I have tired this with an air quality sensor (measuring VOC, PM2.5, and PM10) and found doing this method I had a huge increase in PM2.5 compared to baseline levels (1-2 to 100-280), so I imagine this method would only work well if you have distilled water. I would also be worried about bacteria and mold.
After watching his dishwasher episode I lost all respect for him. He clearly forced that episode and his conclusions were predetermined so he could have a clickbait video title/theme.
Can you elaborate? That episode really worked for me, and fit with my own experience of dishwashers and adding pre wash. My latest machine doesn't have a prewash holder, but does have a prewash cycle on the eco setting - which cleans fine for the majority of my needs - but if things are filthy I through some bicarb in to the machine before I turn it on and it is awesome.
I’m getting ready to hop into some meetings, so here is the short version, I can elaborate more later today.
So he only measured cleaning results after the pre wash cycle and not after the full cycle. Obviously you would expect a short wash with soap to be better than a short wash without. And the results there were a lot closer than I would have expected.
He completely ignored final results while opining that dishwasher tabs aren’t effective without actually testing them side by side.
