Your Centennial windows are designed for easy cleaning.

Cleaning Your Windows

Cleaning windows has to be one of the least popular spring or fall pastimes. But did you know that it’s also the number one reason why some homeowners choose to replace their old, tired, stained and impossible to clean windows?

With Centennial’s famous easy cleaning windows, never again will you have to worry about unsafely climbing ladders, no more buckets, no more storms to take off and on and no more sticky tapes or plastic to keep out the drafts. Instead, by following some very simple instructions, you can help your Centennial windows to look as clean and clear as the day we installed them.

Click on a window style below to learn more about how to clean your windows:

Cleaning Your Double Hung Windows

  • With both sashes locked in the closed position, spray the inside of the top sash (glass) with your favourite glass cleaner and clean the glass with horizontal wipes.
  • Spray the bottom sash with your favourite glass cleaner and clean the glass with horizontal wipes.
  • Now bring a chair close to the window and place the back of the chair about a foot away from the bottom of your window; this will safely hold your window sashes when you unlock and tilt them in to clean the outside of your Double Hung Windows (from the safety and comfort of inside!).
  • Disengage the locks. Lift the bottom sash up about 3 or 4 inches from the bottom sill and pull the top sash down the same 3 or 4 inches. Grasp the locking mechanism on the bottom sash and squeeze them inward to disengage the window. Slowly and safely lower the bottom sash onto the chair back, ensure it is resting securely.
  • Now spray the outside of the tilted-in bottom sash with your favourite glass cleaner and clean the sash in a vertical or diagonal motion (opposite to the inside pane so that if there are streaks, you can easily identify which side of the glass needs a touch up cleaning).
  • When complete, disengage the locking mechanisms on the top sash and lower it slowly and safely down to rest on the bottom sash, already resting safely on the chair back. Repeat the cleaning of the glass as described above. When complete, safely lift and lock in the top sash and then the bottom sash.
  • Close the bottom sash, pushing it firmly to bottom of the window sill and close the top sash pushing it firmly into position at the top of the top sash.
  • Engage the locks and you should see a slight upward and downward motion of the sashes as they are securely pressed into the locked position.

Cleaning Your Side Slider Windows

  • With both sashes locked in the closed position, spray the inside of the left sash (glass) with your favourite glass cleaner and clean the glass with horizontal wipes.
  • Spray the right sash with your favourite glass cleaner and clean the glass with horizontal wipes.
  • Disengage the lock on the centre sash. Slide the left panel to the right about 3 or 4 inches to the centre and slide the right sash left about the same 3 or 4 inches. Grab the locking mechanism on the middle of the right sash and squeeze them inward (up and down) to disengage the window. Slowly and safely pull the right sash into the room.
  • Now spray the outside of the swung-in right sash with your favourite glass cleaner and clean the sash in a vertical or diagonal motion (opposite to the inside pane so that if there are streaks, you can easily identify which side of the glass needs a touch up cleaning).
  • When complete, disengage the locking mechanisms on the left sash and pull it slowly and safely into the room. Repeat the cleaning of the glass as described above. When complete, safely push and lock in the left sash and then the right sash.
  • Close the right sash, pushing it firmly to the right and close the left sash pushing it firmly into position at the left.
  • Engage the locks and you should see a slight left and right motion of the sashes as they are securely pressed into the locked position.

 

Cleaning Your Casement Windows

Cleaning your casement window is a little different than cleaning the tilt-in double hung or side slider style windows.

  • To clean your casement window, you’ll first need to remove the inside screen. Each casement window screen has between 4 to 6 retaining clips that hold your screen securely in position. To remove the screen, turn each retaining clip toward the outside of the window frame while gently holding the middle of the screen with the fingers of your free hand to avoid the screen from falling inward. Once all of the retaining clips are disengaged the screen should fall lightly inside for you to safely remove and set aside. If the screen does not fall freely, grasp the black tabs at the bottom of the screen and gently pull inward to remove the screen.
  • Now, clean the inside of the window, locked in the closed position. Spray the inside pane with your favourite glass cleaner and clean the glass with horizontal wipes using paper towel.
  • Disengage the lock on the sash and crank the window open so that you can now clean the outside of your window. In all but the narrowest casement windows, there should be sufficient room for you to reach out between the frame and the sash to clean the window.
  • Spray the outside of the window pane with glass cleaner and clean the sash in a vertical or diagonal motion – the opposite direction that you cleaned the inside of your window so that if there are streaks, you can easily identify which side of the glass needs a touch up cleaning.
  • Once you’ve completed the cleaning, crank the window closed and engage the lock.
  • Now gently lift and replace the screen pressing it gently back against the window frame and into a secure position.
  • Engage all retaining clips by rotating them toward the centre of the window.
