Spring Cleaning Tips: How to Clean a Double-Hung Window

If you’re like us, you’re looking forward to the end of what has been a very long and dreary winter. Perhaps gearing up for spring cleaning will speed up the arrival of sunny days and warmer weather! When you’re ready to get rid of winter grime on your windows and look out on a fresh new world, here is a simple, step-by-step window cleaning checklist from Renewal by Andersen of Northeast PA.

  1. Clean interior glass. If the temperature is still too cool to open up those windows, start by cleaning the interior glass. Remove interior grilles (if applicable) by lifting them away from the glass near the frame’s edge while leaving the clips in place. Clean the glass with mild soap and water, vinegar and water, or a liquid glass cleaner. Remove the cleaning solution with a squeegee or a clean, lint-free cloth. Avoid using newspaper as it may stain the Fibrex® trim. Rinse with clear water if soap has been used.
  2. Clean exterior glass. To clean the lower sash, unlock the double-hung window and lift it up so your fist easily fits between the bottom of the window sash and the sill. Locate the wash assist tabs on each side of the frame and slide them until they click into the top of the sash (you’ll hear the click). Place both hands on the lower sash close to the tabs and pull firmly toward you. Carefully rest the sash on a chair or other sturdy object. Next, slide the wash assist tabs back to the top of the frame and lower the upper sash. Move the tilt-wash mechanisms, located at the top of the upper sash, inward while pulling the upper sash toward you. Gently rest it on the lower sash. Now you are ready to clean both sashes.
  3. After cleaning your windows. To return the sashes to their original positions, start by lifting the upper sash until it snaps firmly back into place. Then lower it about an inch before sliding it to the top of the frame. Lift the lower sash until it snaps in place (you’ll hear a sound indicating that the balancers are reengaged and your upper sash will stay in place). Then lower it about one inch before sliding it towards the top of the frame.
  4. Replace grilles. If you removed interior grilles, replace them by placing them against the glass and firmly pressing all along the grille and into the grille clips. The grille should fit snugly against the glass.
