METAL MARKS ON DISHES AND
GLASSWARE
POSSIBLE CAUSE:
♦
If a metal item, especially aluminum,
touches a dish in the dishwasher, small
black or gray marks or streaks may be
left on dishes or glasses. A metal mark
can be transferred from the racks in the
dishwasher to other dishes. Washing
disposable aluminum containers such
as pie pans in the dishwasher may
result in metal marks since these items
are lightweight, the washing action
may move them. However, most
metal marks occur during normal use
when dishes come in contact with
flatware.
SOLUTION:
Load the dishwasher carefully to
prevent metal items from touching
other dishes.
TO REMOVE:
Try Zud∗ or Delete∗ with a wet cloth,
sponge or paper towel. Follow
directions on package.
DISCOLORATION OF SILVERPLATE
POSSIBLE CAUSE:
♦
When silverplate takes on a copper or
bronze color appearance, the
silverplate has worn thin and the base
metal is showing through. The
combination of dishwasher detergent
and lack of hand toweling may result
in discoloration of this base metal.
SOLUTION:
The discoloration can usually
be removed be polishing with a silver
polish or by soaking in vinegar for 10
minutes. This treatment is temporary,
however, and only replating with silver
by a jeweler will correct the problem.
TARNISHING OF SILVERWARE (STERLING
OR SILVERPLATE)
POSSIBLE CAUSES:
♦
Sulfur in the water supply. The
effect may be accelerated by automatic
dishwashing because of the higher
water temperature and because the
usual towel drying has been
eliminated. Since sulfur cannot be
readily removed from the water
supply, frequent polishing is the only
answer.
♦
Contact with foods such as
mayonnaise and eggs. If silver has
been in contact with such foods, it
should be rinsed thoroughly as soon as
possible after use, either by hand or
using Rinse & Hold if the dishwasher
is not to be run immediately after the
meal.
