His video about dish washer pods explain they also work significantly worse since your dishwasher was designed with a pre-rinse area to use soap twice during a cleaning cycle. A pod will not be able to be used twice and leaves dishes dirtier.
I don't understand, the pod goes into the same spot as the powder though? It shouldn't matter if its wrapped in a little membrane since a the end of the day you are putting in the same amount of powder into the same spot. The cascade pods at least are just powder aliquoted out for you.
Not saying this is the case as I don't know what dishwasher you have, but one of the points of the video is that this recommendation is often part of a marketing deal and as such shouldn't be trusted. I think it'd say in small print in the manual if this is the case.
Except that it’s also way more expensive and wasteful (edit: both because you have to buy them more often and because each pod is more packaging and the packaging for all of the pods has to be sealed, unlike powder in cardboard…) than just grabbing the powder. If the discomfort from using powder over plastic pods is anything more than completely trivial to you, I’m not sure we can communicate meaningfully on this subject matter.
The tablets I use are wrapped into some kind of wrapper that dissolves in the dishwasher (I think it's some sort of gelatin) so there's no real waste other than the bag they came in. A big bag of tablets lasts me over a year so I really see few downsides here.
To me that sounds like you don’t use your dishwasher that often. Which is fine, good even. But the thing is, for me, the box of powder lasts like, multiple times longer. If a huge bag of pods lasted me a year, I can only imagine the powder would last three. Across the whole industry, the trivial increase in plastic waste instead of less cardboard waste is probably quite colossal, and all for basically nothing.
