Rust spots on cutlery

Rust spots on cutlery - Washing with rusting items or non-resistant cutlery

Bosch · Dishwashers Series 6

What does Rust spots on cutlery mean?

Rust spots appear on cutlery after washing. This can happen if rust-prone items are washed together with the cutlery, or if the cutlery itself is not sufficiently rust-resistant.

Common Causes

  • Cutlery may also rust if washed together with rusting items.
  • Cutlery is not sufficiently rust-resistant; knife blades are often more severely affected.
