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 Ami(R)) or a glass
polish containing Cerium Oxide.
CAUTION:
Do not use any materials containing quartz or silicate abrasives. Typical examples of abrasive cleansers include (Ajax(R), Comet(R), Soft-Scrub(R),
etc). Cleansers with abrasives will scratch the glass surface and cause irreparable damage.
