Cleaning the exterior glass from the interior
You can tilt both sashes of the double-hung window to the interior of the room for easier cleaning of
the exterior glass.
1. Unlock and slightly raise the lower sash. Release the tilt latches located on the top of the lower sash,
and pull the sash toward the interior of the room.
2. Carefully tilt the lower sash until it rests on the trim.
3. Pull down the upper sash until you can put your hands comfortably and safely on the top of the sash.
4. Release the tilt latches on the top of the upper sash, and pull the sash toward the interior. Carefully lower
the upper sash to rest against the lower sash.
5. Clean the exterior glass of the upper sash, then lift and rotate it upright. Push it back into its normal operating
position while pulling the tilt latches in. Reengage the latches. Raise sash to a fully closed position.
6. Clean the exterior glass of the lower sash, then lift and rotate it upright. Push it back into its normal
operating position while pulling the tilt latches in. Reengage the latches. Lower sash to a fully closed position.
CAUTION: Sash may be heavy.
For exterior glass cleaning solution, follow the “Cleaning the glass” steps on page 1.1.
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® (SerVaas Laboratories) to a clean, wet cloth — or apply 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 1.1.
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 (see page 1.1) 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 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.
