> as far as I know dishwashing machines just spray hot water and detergent on everything

There's a couple of sources:

- The dishwasher tablets have a mildly abrasive substance

- The water itself (especially in the UK) can carry abrasive substances from the pipes

If it was in the pipes, handwashing would do it too.

Dishwasher detergent does not contain abrasive substances; dissolve a teaspoon of it in a glass of hot water and see for yourself.

I’m not convinced because I can run pellets over a surface by hand and not scratch it, yet a shot blast will strip paint off easily.

Same substances with different processes produce different results.
