Discussion:
Circular patterns may appear on the glass which are visible mostly when the glass is moist or
fogged up. The size varies from 2-6 inches and are typically described as “rings” or “circles”
that won’t clean off with standard glass cleaners.

To determine if this type of mark(s) is present use a clean, moist cloth lightly wet the surface
of the glass component. Carefully observe if these circular marks develop as the water from
the cloth dissipates. Repeat this process on both the inside and outside of the glass
component (if applicable) to identify which surface of glass (inside or outside) has the
condition. If the marks are present on the outside of glass, this condition will naturally lessen
with sunlight exposure and time. Customer concerns are mostly associated with this condition
being present on the inside surface. If the customer wants the marks removed, they can be
removed using a non-abrasive cleanser or polish. Appropriate materials are Calcium
Carbonate (Bon AmiT) or a glass polish containing Cerium Oxide.

CAUTION: Do not use any materials containing quartz or silicate abrasives. Typical
examples of abrasive cleansers include (AjaxT, CometT, Soft-ScrubT, etc).
Cleansers with abrasives will scratch the glass surface and cause
irreparable damage.

Parts Required:
Qty. Part No. Description
AR NPN Calcium Carbonate (Bon AmiT) or a glass polish
containing Cerium Oxide

Cleaning Procedure: 

1.      Moisten a clean cloth with water.
2. Wipe the glass surface leaving a very fine film of water on the glass.
3. Observe the location of the marks on the glass.
4. If the marks are on the inside of the glass surface, take precautions to cover any of the
interior components the cleanser could come in contact with.
5. Rinse the cloth with clean water.
6. Apply cleanser to the moist cloth.
7. Rub the surface of the glass with the cleanser in a circular pattern being sure to cover
the entire area that the mark involves.
8. Wash off any residual cleanser material with a moist cloth
9. Dry the glass surface.
10. Check that the removal has been successful by rubbing a moistened, clean cloth back
over the cleaned surface and inspect for suction cup marks.
11. Repeat as necessary to remove all of the mark(s) from the glass surface(s).
