Tips for Cleaning Window Glass

Mother and daughter clean a window.Window glass cleaning and care today is more important than ever.

  • Consult with the manufacturer’s specific instructions, especially before using potentially abrasive or caustic cleaners or solvents. Generally, when cleaning glass, it’s a good idea to use a vinegar-based glass cleaner or mild dish soap and water with a soft, lint-free cloth or paper products. You may carefully use a squeegee to dry. Petroleum-based cleaners or solvents should not be used as they can streak the glass and weaken the seal between the glass and frame.
  • Applied film should only be added with approval from the window or door manufacturer. The addition of aftermarket products may void the original manufacturer’s warranty or alter product performance.
  • Clean tracks and weepholes using a dry paintbrush or vacuum brush attachment. The use of oil-based lubricants can damage the weephole. Weepholes help channel water out of the window or door, so be sure they are free of debris.
  • Carefully clean the frame surfaces as directed by the manufacturer. If you live in an area with saltwater or acid rains, it’s a good idea to hose off the exterior of your windows and doors several times a year with water to help protect them from the harsh elements. The use of a razor blade, steel wool, putty knife, or abrasive pad may damage your window.
  • Check weatherstripping, hardware, and caulking and replace broken, worn, or damaged parts. Poor performing components can decrease security or energy efficiency.
  • Reduce the risk of an insecure environment or loss of energy efficiency by leaving windows and doors closed and locked when not in use for ventilation.
  • Choose windows and doors designed and tested to meet stringent air, water, structural, forced entry, and thermal performance standards. Insulating, low-e, or heat reflective glass requires proper maintenance to ensure best performance over the life of the product.
  • Never use a razor blade, putty knife, steel wool, abrasive pad, or anything that may scratch the glass surface.
  • Never use a pressure washer or high-pressure sprayer to wash or rinse windows or doors as this can dislodge seals and gaskets and damage frame components.
  • Clean glass with a vinegar-based cleaner or mixture of mild soap or detergent and water. Rinse completely with clear water, then wipe dry with a soft cloth or a squeegee to help avoid water spots. Always test cleaners in an inconspicuous area first.
  • Avoid washing glass in direct sunlight to reduce streaking of the glass.
  • Avoid abrasive, petroleum-based, or caustic cleaners because they may cause permanent damage to the finish or the glass.
  • When painting, staining, or finishing sash or frame components adjacent to glass surfaces the use of masking tape on the glass is recommended to protect it from splatter or overcoat that may require excessive clean-up.
  • Clean screens by gently vacuuming with a brush attachment. Or, remove for cleaning and gently vacuum or wash on a flat, clean surface with mild soap and water and a soft brush. Rinse, wipe, or air dry and reinstall.

Condensation on Window

 

CAUSES AND REMEDIES

WHAT IS THIS WATER ON MY WINDOWS?

Window Condensation — Water or frost on windows is condensation. Condensation is formed when warm moist air comes in contact with cooler dry air. An example of this is when a bathroom mirror “steams up” after a hot shower. Just like that mirror, the inside or outside of your window can sweat or fog because of temperature differentials.

ARE MY WINDOWS TO BLAME?

Faulty windows do not cause window condensation. Glass is usually the first place you notice condensation because glass surfaces have the lowest temperature of any surface in a house.

THEN WHAT’S THE CAUSE?

The moisture in the air causes window condensation. The reason you may observe more condensation in your home is of modern energy-efficient homebuilding techniques and products. The insulation and construction materials used today are designed to keep cold air outside. This is especially true of new windows. While energy-efficient designs and weather-stripping keep cold air outside, they also keep the warm moist air inside. Older window designs were less efficient and consequently allowed moisture to escape. If you didn’t have as much condensation before replacing your old windows, it’s probably because they were drafty. Good windows and insulation all create barriers to the air exchange of a home. When combined with the additional water vapor (moisture) from showers, cooking, or from clothes dryers not vented to the outside, the result is excess moisture and a high relative indoor humidity level.

HOW CAN WINDOW CONDENSATION BE REDUCED?

The key lies in controlling the humidity inside your home. First, let’s understand where the moisture comes from. During the hot humid summer, your house absorbs moisture. The same principle applies to a newly constructed or remodeled home, due to the abundance of moisture from the building materials used in construction. During the beginning of the winter when you start to heat your home, condensation occurs. After a few weeks, your home will begin to dry out and you’ll see less condensation. Opening a window briefly is a quick temporary solution. The drier cold air will enter the room while the moist air is allowed to escape.

Other solutions that may reduce window condensation include:

  • Cracking open a window or door daily to air out your house.
  • Opening a window or running exhaust fans longer in the kitchen, bathroom and laundry room.
  • Opening drapes and blinds, allowing air to circulate against windows.
  • Turning off any humidifying devices in your home.
  • Installing and using a dehumidifier.

If you live in a northern climate, the above steps, as well as the following points, may be relevant:

  • Adding storm windows or replacing existing single-pane windows with insulated windows.
  • Keeping plants in a sunroom or in rooms that are infrequently used during extremely cold weather.
  • Adding waterproofing protection to basement floors and walls.
  • Removing radiator pans until sweating has been eliminated.
  • Making sure that open-faced gas heaters are connected to a chimney and using them as little as possible.

WHEN SHOULD I BE CONCERNED ABOUT WINDOW CONDENSATION?

Window condensation should only occur when there are extreme temperature differences between indoor and outdoor spaces. In addition, there should only be a fairly small amount of water on the glass. Condensation will be seen on the inside of a window during winter months and will present itself on the outside of a window during summer months. If you find condensation between the two layers of glass in an insulated window, the airtight seal has probably been broken and the glass will need to be replaced. If there is too much moisture inside the home, you will see evidence during both the cold and warm seasons. Moisture spots on the ceiling or walls, peeling paint, rotting wood, delaminating plywood, moisture on exterior walls, and fungus, mold or mildew growth are signs of a more serious moisture problem. Should you experience these symptoms, an expert heating & cooling contractor should be contacted in order to solve the problem.
