Problem:
May be caused by:
What to do:
Washing copper with sterling silver
Yellow film on sterling silver results when you wash
copper utensils in same load. Silver polish will
usually remove this type of stain.
Yellow or brown
marks (cont.)
Tea or coffee (tannic acid) stains
Remove tea or coffee stains by hand using a
solution of ½ cup bleach and 3 cups warm water.
(Do not use on sterling silver or silver plate.)
Allowing salty or acidic foods to remain
on flatware
Rinse flatware that is to stand several hours before
washing.
Do not put stainless steel and silver flatware in the
same silverware basket compartment. Direct contact
to stainless steel can cause permanent damage to
silver.
Clean stained items with silver polish.
Discoloration of
stainless steel, silver
plate
Stainless steel contacting silver
Do not use abrasives on stainless steel or silver.
Distortion of plastics Plastic item not dishwasher safe
Do not wash plastic items in dishwasher that are not
“dishwasher safe”.
Marks on melamine
and plastics
Porous material
Use a special cleaner for plastic.
Do not use bleach or scouring powder on these
materials.
To remove cloudy film, try a vinegar rinse:
•
Wash and rinse load as usual.
•
Remove all metal items from dishwasher. Do not
add detergent.
•
Pour 2 cups of vinegar into a bowl and set it on
bottom rack.
•
Run dishes through an entire wash program. If
the vinegar rinse does not work, repeat process
substituting ¼ cup of citric acid crystals (available
at most drug stores) for the vinegar.
If vinegar or citric acid rinse does not remove film,
the cloudiness is "etching". This is permanent. To
prevent etching, if you have soft water, try using
only 1 teaspoon of recommended dishwasher
detergent.
Too much detergent, especially in soft
water
Use a good quality dishwasher detergent and rinse-
aid. Do not overload dishwasher. Water should
circulate freely to assure adequate rinsing and
draining.

of glass
Rinse aid used with soft water
