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
- ThePowerOfFuet 2y agoIf 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.
- scott_w 2y agoI’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.
