of different materials contact each other (e.g. knife blade and
handle). At the contact point cracks and splits can develop in
the lower grade metal as the electrochemical properties of the
two materials are different and galvanic corrosion can develop.
First signs of such corrosion are dark discoloration and rust
marks at the contact point.

become attached to the surface of rust-free metal. Possible
sources are:
a. Damaged dishwasher baskets:
A damaged basket can act as a rust carrier if the metal
tines under the plastic coating have begun to rust.
b. Rusting steel:
In addition to non-dishwasher-proof knives and damaged
blades, the fixing screws on the handles of pots and pans
may not be rust free and can be sources of rust.
c. Damaged enameled kitchen appliances/pots:
Damaged or poorly enameled areas (e.g. under the
handle of a pot) may, after contact with water, develop
rust, which is then spread during the wash cycle.
d. Mains water with high iron content:
Very rare.
