Rinse or scrape? I think the pre-rinse crowd is costing us repairs

I keep seeing people online say you have to rinse every plate before loading, but my buddy who does warranty work in Denver told me most detergent needs some food particles to activate properly. On the flip side, I left a bowl with baked-on cheese in my Whirlpool last month and it clogged the spray arm after 3 cycles. So which is it? Are you team scrape-only or team pre-rinse, and have you actually tested both ways on your own machine?

Bought a used Bosch off Craigslist and tested both ways for a month - scrape only worked better but only if I ran the hot water in the sink before starting the cycle.

Oh wow, I totally get why you'd think that but I had the opposite experience with my Bosch! I tested both ways for a few weeks and found prerinsing actually got me cleaner dishes without having to mess with the hot water trick. Maybe it depends on the model or how old the machine is, but mine just seemed to handle caked-on stuff way better when I gave them a quick rinse first.
