Washing windows is one of those once- or twice-a-year tasks you might not think about, but it can really make a big difference in how your windows look when you take the time to clean them. Depending on the type of windows you have, the task might be easier than you think, and you can save money by doing the job yourself instead of hiring a pro.

How Do You Wash House Windows?

The materials you need for window washing can be purchased at any home store, and you may have some of these things already in your basement or garage.

Things You'll Need

Water bucket
Squeegee
Cloth rag
Window scrubber
Microfiber towel
Drop cloths, if washing windows inside
Spray bottle

Washing Windows on the Outside

Add a small amount of dishwashing detergent to your water bucket and fill with cold water from a sink, hose or bathtub.

Using a damp cloth rag, wipe down the exterior window frame.

Dunk a window scrubber into the water bucket and wring out any excess water. Then, use the window scrubber brush to clean the glass portion of the window, removing all dust and dirt.

Next, take your squeegee and use it to wipe off the excess water from the glass. Be sure to wipe horizontally in the same direction each time. Start at the top and wipe across the whole window. Use a dry microfiber towel to dry the squeegee between passes. This will help minimize streaking.

If you'd rather wipe the glass vertically with the squeegee, just create a dry edge at the top of the window glass first with a microfiber cloth. Then, place the dry squeegee on the dry edge you made and wipe down vertically down the whole window, still drying the squeegee in between passes.

For Windows With Individual Panes

If your windows have individual panes with wood dividing the glass, use the window scrubber brush first to wash each individual window pane (likely a smaller one). Then, use a small squeegee to wipe the glass, but instead of letting the water drip off, hold a microfiber towel along the bottom edge of the squeegee so it can capture excess water and it won't damage the wood.

Washing Windows on the Inside

When window washing inside, set a drop cloth on the floor to catch any excess water or soap. Instead of using a water bucket, fill a spray bottle with a small amount of dishwashing detergent and water. Spray the interior surfaces of the window, use a cloth rag to clean and dry it with a microfiber towel.

If you have windows that tilt toward the inside of your house, you can clean the exterior part of the window the same way you would the interior part because you don't have to go outside. The instructions above are for cleaning windows outdoors when windows are stationary and can't be tilted inside.

DIY Window Washing Solutions

If you find dish detergent and water aren't as effective as you'd like, there are alternative solutions you can mix with ingredients you may already have at home.

White vinegar and water: Because vinegar is acidic, it can be a good choice for breaking up film and grime that might accumulate on your windows. Mix 1 part vinegar with 10 parts warm water in a spray bottle.
Rubbing alcohol: This makes an excellent solvent for stubborn stains. You can add a little bit to your vinegar/water spray bottle if you want an extra boost to your cleaning solution.
Essential oils: For making your solution smell clean and fresh, consider adding a drop or two of your favorite essential oil. Don't overdo it or your solution will leave grime behind on your windows. A drop or two is all you need. Lemon essential oil is a great choice for a clean, fresh scent.

How Often Should You Wash Your Windows?

In general, you should clean your windows about twice yearly with the steps described here for a full residential window cleaning. But you can also clean them when you notice dirt or other smudges, such as from children or pets peeking out the window. It may also depend on where you live or what season it is. If you live in an area with lots of pollen or pollution, for example, you may need to clean them more often.
