How to Clean Double-Hung Windows

Double-hung windows are the most popular style of windows. They have two sashes that slide up and down independently--one at the top and one at the bottom of the window. They are designed to make cleaning easier. However, attempting to open both sashes to clean is not as easy as it sounds. This article covers how to properly open and close both sashes of a window to clean a double-hung window.

Double-hung windows, like those seen here, are designed to slide up and down independantly.

Step 1

Remove the screens from the windows.

Step 2

Unlock and raise the lower sash 2 to 3 inches.

Step 3

Take a moment to vacuum or clean out the bottom sill of the window.

Step 4

Grip the tilt-latches/sash releases and slide them inward while pulling toward you. If your window does not have tilt latches, push the right jambliner (the frame the window runs on) towards the wall while pulling on the upper corner of the sash. Then, repeat on the left side.

Step 5

Tilt the lower window so that it rests on the lower sash. For best results, have a chair or stool next to the sill to help support the window.

Step 6

Lower the upper sash until you can comfortably reach the top of it or so it is a few inches above the lower window.

Step 7

Find the tilt-latches/sash releases at the top of the window and slide them inward while pulling toward you. If your window does not have tilt latches, push the right jambliner (the frame the window runs on) towards the wall while pulling on the upper corner of the sash. Then, repeat on the left side.

Step 8

Carefully lower the upper sash until it rests on top of the lower sash.

Step 9

Clean the exterior glass of the upper sash using plain water or a solution of 2 to 3 tablespoons vinegar to 1 gallon of water.

Step 10

Wipe down the frame and jambliner of the upper sash with a mild detergent and water if necessary. Use a squeegee or dry the windows with a lint-free cloth or paper towels.

Step 11

Carefully lift and rotate the upper sash until it clicks into place. You may need to push the tilt lashes in as you do so. Do not use too much force or you may end up forcing it past it's original position.

Step 12

Push the upper sash down a few inches and then lift it back into its original position. Pushing it down helps to re-engage sash balance. If you don't do this, the upper sash may fall.

Step 13

Clean the exterior glass of the lower sash using plain water or a solution of 2 to 3 tablespoons vinegar to 1 gallon of water. Use a squeegee or dry the windows with a lint-free cloth or paper towels.

Step 14

Wipe down the frame and jambliner of the upper lower with a mild detergent and water if necessary.

Step 15

Lift and rotate the upper sash until it clicks into place and push it back into position. Again, you may need to push the tilt lashes in as you do so.

Step 16

Clean the interior side of the glass using plain water or a solution of 2 to 3 tablespoons vinegar to 1 gallon of water. Use a squeegee or dry the windows with a lint-free cloth or paper towels.
