Cleaning the exterior glass from the interior
You can remove the venting sash of the sliding window for easier cleaning of the exterior glass. Unlock the
window and slide to the fully open position. Ensure that the sash has cleared the anti-lift clip located at the top
of the frame. Grasp the sash, and lift up and out of the bottom track.
CaUtiOn: sash may be heavy.
Lay sash flat to wash the exterior glass on the vent panel. To wash the fixed panel from the interior of the
building, remove the screen and reach out to wash the exterior glass.
CaUtiOn: Do not extend your body out of the window. if the entire glass of the fixed panel cannot be reached from the interior of the building,
wash the fixed panel from the exterior of the building.
For exterior glass-cleaning solution, follow the "Cleaning the glass" steps on page 3.1.
spot-cleaning stubborn materials on all glass
To remove any markings from grease, oil, tape adhesive, crayons or paint, or marks from plastics that may have come in contact with
the glass:
1. Apply a small amount of a nonabrasive cleaner such as Bar Keepers Friend
a solvent such as acetone or mineral spirits to a clean, dry, lint-free microfiber cloth or paper towel.
2. Rub on the areas of glass that need spot-cleaning. Avoid getting any cleansers or solvents on the vinyl frames as they may discolor
the finish.
3. Wipe clean using a clean, dry, lint-free microfiber cloth or paper towel.
4. Then clean the glass as mentioned on page 3.1.
CaUtiOn: Do not use a razor blade to scrape off stubborn materials — doing so may leave permanent marks on the
glass or scratches that could cause glass breakage. Contact the Pella window and Door showroom nearest you for
special cleaning instructions.
Cleaning flat screens
To clean a flat fiberglass screen, either remove the screen and gently wash it with soap and water, or use the
drapery brush attachment on your vacuum cleaner.
CaUtiOn: Use caution when children or pets are around open windows and patio doors. screens are not
designed to retain children or pets.
Cleaning the weep system
It is normal for water to accumulate in the sill and track. The water is intended to drain to the outside
via the drainage or "weep" holes. Check to make sure that the weep holes are clear of obstruction
(dirt, sand or building materials). To clean the weep holes, use a small, soft brush to clear the opening.
Weep holes are located both inside and outside the window in the bottom of the frame. If the window
is "stacked," there may be weep holes between the units.
Cleaning the interior and exterior frame and sash material
Begin cleaning by vacuuming dirt from the sill and track areas. Then wash the window frame and sash with a mixture of mild dish soap and water.
warning: Do not use abrasive or caustic solvents as they may damage your windows. Do not scrape or use tools that might damage the surface.
Do not power-wash.
Cleaning the hardware finish
A soft cloth and mild cleaner may be used on all hardware finishes for vinyl sliding windows.
