How to Clean Andersen Double Hung Windows

Andersen double-hung windows are some of the most popular window designs in the United States. The name is derived from the fact that they are made with two sashes and two panes of glass. Each sash can be raised and lowered independently in order to open and close the window.

Andersen double-hung windows come in many different sizes and styles, but they all share certain characteristics that make them easy to clean. 

Here are some tips for keeping your Andersen double-hung windows clean and clear:

  •         Before you begin cleaning, use a vacuum to get rid of dust and dirt around the window area. Remove carpets if possible, or cover areas with tarps before working on them so that water does not drip on them
  •         Position a chair so that its back is facing the window. This will be useful later when you’re ready to clean the windows.
  •         Use Windex or other glass cleaners to remove dirt, grease, and fingerprints from glass surfaces.
  •         Don’t use a squeegee. It will scratch the glass, which is no good! Instead, use small paper towels to dry the window as much as possible before it dries on its own
  •         Wipe down the window hardware with a soft rag or paper towel

How to Clean Andersen Double Hung Windows

If you’re looking for a way to improve the look and feel of your home, replacing your windows is a great place to start. But before you make the plunge, it’s important to know how to properly clean them.

The first step in cleaning double-hung windows is to check and see if you have removable interior grilles. If so, remove them by lifting their edges away from the glass while leaving each grille clip in place. Then clean the grilles with a soft, dry cloth.

To clean the exterior of your windows, begin with a lower sash. Unlock it and raise it up about two inches.

Next, find the wash assist tabs located above each window sash. Slide them until they wedge between the frame and glass.

Then, grip the lower sash on both sides of the window and pull it towards you, tilting it inward. Keep tilting the sash so that it rests on a durable object like a chair, but don’t tilt beyond 90 degrees.

After that, you can move to the upper sash.

Leave the lower sash in its full-open position, then slide wash assist tabs (the same ones used for opening the lower sash) up the frames’ topside.

By lowering the upper sash until there is at least an inch of space between it and the lower one, you will be able to reach the title-wash tabs that are located on top of each window.

Next, while pushing the lower sash inward and pulling up on the upper sash, carefully tilt it until it rests flat against the bottom pane.

You can now clean both the lower and upper parts of your windows.

To close the window, raise the upper sash halfway and then push it down so that it snaps into place into a fully vertical position. Then, gently guide the upper sash to its full extension before closing it completely along its entire length.

How to Clean Andersen Double Hung Tilt Wash Windows

First, unlock the window and lift it up.

When tilting the window sash into your home for cleaning purposes, make sure that it’s level before trying to reset it back in. If the sash is uneven, you’ll have a hard time getting this done without causing damage to the unit.

To tilt the window sash into place, first, retract its lock by pushing outward on them (usually, there will be little bumps where they are located).

Then, pinch the clips in so that the window tilts in. Place a chair or another object next to the window to help support it as you clean. When finished, lock the window back into place by pushing inward on the locks and then pushing them back into their original positions.

If your windows are old or have been painted over multiple times, they may be difficult to tilt open. This is because they can become stuck in place due to paint build-up around their edges. You can try using a bit of WD40 or other lubricants on those areas where you think there might be friction in order to remove it.

Tips For Cleaning Double Hung Windows

If you want to keep your home’s windows looking their best, it’s important to clean them regularly. Here are some tips:

Clean Your Windows Regularly

You don’t have to do this every week (although if you do it weekly, it will be easier). Just remember that the more often you clean your windows, the easier it will be! If you wait until they get really dirty before cleaning them, it will take more time and effort than if you just wash them once a month or so.

Use The Right Cleaners

You don’t want to use just any cleaner on these windows because many types of cleaners can damage the finish on your window or even leave streaks behind when they dry! You should only use products specifically designed for cleaning glass (like Windex) or other safe products like vinegar and water solutions.

It’s best if you avoid using abrasive cleaners because they can scratch the surface and leave marks behind on your glass panes.

Safety First!

Before you start cleaning your double hungs, make sure you’re following all safety precautions.

Some windows have screens on them that may need special treatment or maintenance. In addition, many double-hung windows do not have locks on them, so they should be locked while they’re open to prevent accidents.


There are many different ways to clean windows, but if you have the right tools and know-how, cleaning them can be done in just a few minutes. You’ll also be able to save yourself from having to buy new windows or pay someone else for their services if you do this on your own.
