How to Clean Sliding Windows

Unlock the window by locating the locks on the sides of the sashes. Fully open the window to allow easy access to both sides of the glass as well as the tracks along the top and bottom of the frame.

Lift the window up and out to disengage it from the bottom track. Tilt the bottom of the window toward you until it clears the frame. Lay it flat on the ground. Do the same for the other window.

Use a soft-bristled brush to remove any debris, dust, or cobwebs from the frame and tracks of the window.

Repeat steps 4 through 7 for both sides of the windows.

Spread your cleaner of choice on the window. If using a soapy or vinegar solution, use a sponge or cloth to soak the glass. If using a glass cleaner in a spray bottle, spray it across the window. Regardless of which solution you use, allow it to sit for a few minutes to loosen up dirt and grime.

Using the soft-bristled brush, gently scrub the glass in a circular motion. Be careful not to apply too much pressure, as this can scratch or damage the glass.

Using a squeegee, start at the top of the window and pull the cleaning solution down towards the bottom of the window. Wipe the squeegee clean after each pass. Once you have removed all of your cleaning solution from the window, use a microfiber cloth or chamois to wipe the remaining water from the glass.

Use a microfiber cloth or chamois to dry the window and prevent streaks or water spots from forming.

Using a cloth or sponge and your preferred cleaning solution, clean the frame of the window. For stuck on dirt, allow the solution to sit momentarily before breaking it up with your brush.

Wipe the tracks your window uses to slide back and forth with a cloth or sponge. Use your cleaning solutions and brush to break up any caked on dirt or debris.

Once the frame, tracks and windows are clean and dry, insert the top part of the sash into the frame and rotate the bottom part of the sash into place. Slide the window and lock it to make sure it operates and fits correctly.
