Things You'll Need:
- White vinegar
- Paper towels
-
Step 1
Tilt the window out. The method of doing this depends on the type of double hung windows you have. Some windows have a top latch that must be released in order to tilt the windows. Others must be raised to a certain point then tilted out.
-
Step 2
Clean the outside of the window using horizontal strokes using plain white vinegar and paper towels. Once you do this, put cotton gloves on to prevent fingerprint markings.
-
Step 3
Spray plain vinegar on a paper towel. Wipe the interior of the window using vertical strokes. Dry the glass with a clean paper towel.
-
Step 4
Inspect the window for streaks or smudges. If they are top to bottom, they are on the interior and need to be addressed before replacing the window. However, if they are side to side, they can be addressed after the window is replaced.
