Before You Begin

The instruction steps are below but if you're not sure you want to do the job, click Home Advisor, a free referral service that connects homeowners with prescreened local contractors, and type "clean windows" in their Find Pro search box.

  • Step 1 : Assemble materials

    Use a commercial window cleaner like Windex or make your own with a solution of 1/2 cup of household ammonia to one gallon of warm water. Choose between putting the solution in spray bottle or a bucket. You can use clean lint-free cloths or rags or a squeegee to wipe the glass surface. A stepladder with a shelf is a handy way to reach high windows.

  • Step 2 : Clean interior window frames

    Use a rag to wash window frames and screens before washing windows to help the glass stay clean longer. If they are greasy and dirty, use a household cleaner.

  • Step 3 : Clean the window glass

    Clean the window glass Work from the top to the bottom of the window so drips don't fall on work you've done. If you like using a spray bottle, squirt the solution on the glass and use a scrubber or lint-free cloth to scrub the glass and wipe off the solution.

    Clean the window glass

    To dry the window without rags use a squeegee with a study nick-free blade. Put it in the top left corner and drag it horizontally to the right corner. Then swivel back to the left going back and forth until you reach a lower corner. Use the cloth to wipe the solution along the length of the window. If you didn't use a squeegee, dry the glass with a clean dry lint-free cloth or paper towels.

    To see which side streaks are on, use horizontal strokes washing inside windows and vertical strokes washing the outside of them (or vice versa).

  • Step 4 : Clean the exterior of the windows

 ++Step 4: Clean the exterior of the windows Before cleaning the window glass outside, wash the storm and/or screen window and clean out the window sill area. Remove any leaves or debris that accumulates in corners and wash the surface with a household cleaner if there's greasy dirt. Then wash the window frames as you did inside.

 ++Step 4: Clean the exterior of the windows

    Use the same process of cleaning as you did inside. Be mindful of using a washing stroke that's opposite what you did inside so you can find any streaks you might have created. Be careful when you're working outside, especially if you're climbing a ladder and challenged by shrubbery that's in the way.
