GLASS CARE AND MAINTENANCE
GENERAL OVERVIEW AND CONTACT
Boyd Windows are tested, manufactured, and supplied in accordance with AAMA standards, specifications, and
requirements; however, Boyd Aluminum cannot protect against adverse environmental conditions or extreme or
unusual use of the products provided in the field. The information contained in this manual has been compiled for
general and typical window types. Boyd cannot warrant or guarantee products that are used in any manner other
than normal use, and results may differ from those expressed in this manual. Due to custom applications, design,
and specifications of this industry, some of the information may not apply and should be analyzed and reviewed
before action is taken. Users of material should conduct their own tests to verify that the material is applicable for
the field application.
In the event that a part or piece has broken or become defective, please contact you contractor or installer, who will
send requests for information or possible replacement.
1. GENERAL CLEANING
Glass should be washed, rinsed, and dried during the different phases of construction. This will help prevent the
accumulation of foreign debris from adhering and distorting the glass from its original quality. For most glass, except
specialty or coated glass, use mild soap and clean with soft and particle-free cloths or sponges. A slightly acidic
cleaning solution can be used on glass, but it must be immediately rinsed with clean water. Use of a rubber squeegee
for streak-free viewing is acceptable. Check with the project glass manufacturer for specific cleaning instructions.
2. PROPER PROCEDURES FOR CLEANING ARCHITECTURAL GLASS PRODUCTS - PUBLISHED BY THE
GLASS ASSOCIATION OF AMERICA (GANA 01-0300)
Architectural glass products play a major role in the comfort of living and working environment(s) of today’s homes
and commercial office spaces. By providing natural daylight, views of the surroundings, thermal comfort, and design
aesthetics, glass usage and condition often affect our selection of where we live, work, shop, play, and seek education.
Architectural glass products must be properly cleaned during construction activities and as a part of routine
maintenance in order to maintain visual and aesthetic clarity.
As dirt and residue appear, interior and exterior glass surfaces should be thoroughly cleaned. Concrete or mortar
slurry that runs down (or is splashed on) glass can be especially damaging and should be washed off as soon
as possible. Before proceeding with cleaning, determine whether the glass is clear, tinted, or reflective. Surface
damage is more noticeable on reflective glass as compared with the other glass products. If the reflective surface
is exposed, either on the exterior or interior, special care must be taken when cleaning, as scratches to the reflective
glass surface can result in coating removal and a visible change in light transmittance. Cleaning tinted and
reflective glass surfaces in direct sunlight should be avoided, as the surface temperature may be excessively hot for
optimum cleaning. Cleaning should begin at the top of the building and continue to the lower levels to reduce the
risk of leaving residue and cleaning solutions on glass at the lower levels. Cleaning procedures should also ensure
that the wind is not blowing the cleaning solution and residue onto already cleaned glass.
Cleaning during construction activities should begin with soaking the glass surfaces with clean water and soap
solution to loosen dirt or debris. Using a mild, non-abrasive commercial window washing solution, uniformly apply
the solution to the glass surfaces with a brush, strip washer, or other non-abrasive applicator. Immediately following
the application of the cleaning solution, a squeegee should be used to remove all of the cleaning solution from the
glass surface. Care should be taken to ensure that no metal parts of the cleaning equipment touch the glass surface
and that no abrasive particles are trapped between the glass and the cleaning materials. All water and cleaning
solution residue should be dried from window gaskets, sealants, and frames to avoid the potential for deterioration
of these materials as the result of the cleaning process.
The ability to detect certain surface damage, i.e. light scratches, may vary greatly with the lighting conditions. Direct
sunlight is needed to properly evaluate a glass surface for damage. Scratches that are not easily seen with a dark or
gray sky may be very noticeable when the sun is at a certain angle in the sky or when the sun is low in the sky.
The glass industry takes extreme care to avoid glass scratches by protecting all glass surfaces during glass
NOTE: Since glass products can be permanently
damaged if improperly cleaned, glass producers
and fabricators recommend strict compliance
with the following procedures for properly cleaning
glass surfaces.
NOTE: It is strongly recommended that window
washers clean a small area or one window, then
stop and examine the surface for any damage to
the glass and/or reflective coating.
