How to Clean Window Screens (Without Damaging the Mesh)

The safest way to clean window screens is to take them out, lay them flat, and wash them with mild dish soap, warm water and a soft brush, then rinse with a gentle hose spray and let them dry completely before they go back in. No pressure washer, no stiff brush, no harsh cleaners. For a quick touch-up between washes, you can vacuum screens in place with a soft brush attachment.

Screens catch dust, pollen and cobwebs all year, and a dirty screen makes clean glass look dull. Fall is a good time to do them: after a dry, windy stretch, and before guests arrive for the holidays.

What you’ll need

• A vacuum with a soft dusting brush attachment
• A bucket of warm water with a small squirt of mild dish soap (about a teaspoon per gallon is plenty)
• A soft-bristle brush or a non-scratch sponge
• A garden hose with a spray nozzle on a gentle setting
• An old towel, tarp or drop cloth to lay screens on
• Painter’s tape and a marker for labeling
• Microfiber cloths

How to clean window screens, step by step

1. Label before you remove. Put a small piece of painter’s tape on each screen frame and note which window it came from. Screens that look identical often aren’t, and a screen in the wrong opening may not seat or lock properly.
2. Remove the screens from inside. Most window screens release with tabs, spring plungers or pull tabs on the frame. Work from inside the house, and don’t lean out of an upper-story window to reach one. If you’re unsure how yours come out, check the window maker’s instructions before forcing anything.
3. Dust both sides. Lay the screen on a towel or tarp and vacuum both sides with the soft brush attachment. Getting the loose dust and cobwebs off first keeps them from turning to mud when you add water.
4. Rinse gently. Spray both sides with the hose on a light setting, holding the nozzle at an angle rather than straight on. A hard, direct stream can stretch the mesh or pop it out of its spline.
5. Wash with soapy water. Dip the brush or sponge and scrub lightly, top to bottom, with small circular motions. Let the bristles lift the dirt off the surface rather than pushing them through the mesh. Give the corners and the frame edges extra attention; that’s where grime collects.
6. Rinse until the water runs clear. Leftover soap leaves a film that attracts dust, so rinse both sides well.
7. Dry completely. Shake off the excess, blot the frame with a microfiber cloth, and lean the screen against a wall or fence to air-dry. Screens often dry within a few hours in sun and a breeze, but wait until they’re fully dry before reinstalling, because a damp screen holds dirt and can encourage mildew.
8. Inspect and reinstall. Before the screen goes back in, look for small tears, loose spline or bent corners. Then return each one to its labeled window and make sure every latch catches.

Quick cleaning without removing the screens

Between full washes, or for screens that are hard to remove, a light clean in place works well:

• Vacuum the screen from the inside with the soft brush attachment, working top to bottom.
• Wipe it with a microfiber cloth dampened in mild soapy water, wrung out well so it doesn’t drip down the sill.
• Follow with a cloth dampened in plain water, then let it air-dry.

A lint roller is handy for lifting dust and pet hair off a small section. This won’t reach grime packed into the weave, but it keeps screens looking good for months between deeper cleans.

Mildew, pollen and stubborn spots

For dark speckling or a musty film, mix white vinegar and water 1:1 in a separate spray bottle. After the soap wash and rinse, spray the affected area, let it sit a few minutes, scrub lightly with the soft brush, and rinse thoroughly. Use the vinegar on its own, not mixed into the soapy water or combined with any other cleaner, and rinse it well off metal frames.

Skip bleach, ammonia and abrasive powders. They can weaken mesh, discolor frames and leave residue, and the mild soap method handles most screens.

What can damage screens

• Pressure washers. The stream is strong enough to tear mesh and bend thin aluminum frames.
• Stiff brushes and hard scrubbing. Fiberglass mesh in particular can stretch or tear if you push too hard.
• Specialty screens. Some ultra-fine or high-visibility screens are designed to be dusted dry only, with no hose or water. If your windows came with a branded or specialty screen, check the manufacturer’s care instructions first. Renewal by Andersen, for example, says its TruScene screens should be cleaned with a duster or soft cloth, not a hose.
• Painting the frame. Andersen recommends against painting insect screen frames. A frame that’s corroded or badly worn is usually better replaced than painted.

How often to clean window screens

Window manufacturers commonly suggest cleaning screens at least once or twice a year, and more often in dusty, high-pollen or salty coastal air. Andersen recommends at least once a year, more in areas with pollutants or salt air, and Renewal by Andersen suggests spring and fall. A quick vacuum in place whenever you dust the blinds or clean the window tracks keeps buildup down between washes.

Screens and tracks tend to get dirty together. If your sliders are gritty or sticking, our guide on how to clean sliding door and window tracks covers the tracks, weep holes and the screen-door track.

When to call someone else

A torn screen, a bent frame or a screen that won’t stay latched needs repair or replacement, not more cleaning; a screen or window repair shop can usually rescreen a frame. For screens on upper floors that can only be reached from outside on a ladder, a window-cleaning specialist is the safer choice.
