and
Window Cleaning
|
|
| Recently, many
clients are requesting LWC Services to assist with the problem of
hard water and acid rain-stained windows. This growing problem has
many causes, among them are rain runoff from precast and masonry building
surfaces, sprinklers, building design and regional water sources.
Previous attempts using corrosive acids have proven unsuccessful.
LWC has developed a series of environmnental-friendly solutions that
restore clear, tinted, and mirror-finished glass without damaging
the glass or its surroundings. |

Problem
Description:
|
| Windows are composed
of compound materials such as silicates, lime and soda. Whenever foreign
minerals such as hard water, lime, and petroleum materials are introduced
to glass, mineral deposits result. If these mineral deposits remain
on glass for a period of time, they begin to adhere to the glass. |

|
Hard
Water Sources:
|
| Many companies
are noticing stains on their buildings' windows that can not be removed
with normal window cleaning. With precast buildings, rain or morning
moisture causes the precast material to become wet. Acid rain, lime
in the precast material, and airborne petroleum blend with the water
and a residue is left on the glass. Water has an affinity to glass
and the rain water and its contents stick to the glass. The sun intensifies
the process causing the minerals to bake onto the glass. |
|
|
Potential
Damage and Replacement:
|
| Because minerals
bond together, the longer these stains remain untreated, the more
severe the problem. Many property owners and managers have been added
to the long list of statistics when it comes to burned, etched, or
windows beyond repair. Since more buliding owners are installing specialized
glass, replacement costs can be very expensive and must be special
ordered causing delays and inconvenience. |

LWC
Services' Solutions:
|
| Frequent window
cleaning is the best preventative maintenance program. If your problem
is more severe, LWC's glass restoration program uses only water soluble
and biodegradable products that are very effective in reconditioning
glass surfaces. These products, unlike acids, do not cause damage
to the window's caulking, seals, or aluminum frames and are safe for
employees and surrounding plant life. |
