It's entirely possible that a cold pre-wash helps avoid staining! But that's not what I'm complaining about.

TC made specific claims about the benefits of a hot pre-wash. Instead of countering those, the blog's author decided to ignore them and build his own strawman to attack.

The author should have refuted the specific claims, or acknowledged them before moving to the drawbacks.

blog author actually discussed it. in form of explaining that hot prewash stains, 85% of cleaning done mechanically, the rest is done with detergent with temperature been supportive (according to published "scientific literature") and that who cares about how things are clean after prewash as long as dishes come out clean after main wash.

in general, it's hilarious. there are literally dozens R&D departments that design dishwashers across dozens of companies. And all of them are wrong because somebody run tests on (checking notes) 30 years old dishwasher.

i trashed dishwasher similar to the one that tests are run on 4 years ago. it was washing everything just fine with exception of few days when check valve broke. after i replaced it, it came back to washing perfectly with cascade platinum pods
