To clean window screens, take them out, brush or vacuum off loose dirt, then wash them with mild dish soap, warm water and a soft brush and rinse with a gentle spray. Let them dry fully before reinstalling. Skip pressure washers and harsh solvents, which can stretch the mesh or pop it out of the frame.
Getting window screens out of the frame safely
Most screens come out from inside the house. Look for small tabs or pull loops along one edge, or spring plungers on the sides. Lift or push toward the spring side, swing the free edge in, and ease the screen out at an angle. Casement windows often have screens mounted on the inside that unclip instead.
Label each screen as it comes out. A strip of painter’s tape with the room name and top or bottom spares you from test fitting every screen in every window later, because screens that look identical often differ by a fraction of an inch. Work on a clear patch of lawn, a driveway or an old sheet so you are not grinding grit into the mesh from underneath.
Before washing, lay each screen flat and look for small tears, loose spline (the rubbery cord that holds the mesh in its channel) or bent frames. A wash will not fix any of those, and a hose aimed at a loose corner can make it worse.
A soap and brush wash for window screens
- Knock off loose debris first. A soft brush, or a vacuum with a brush attachment, lifts cobwebs and dust before water turns them to mud.
- Mix a bucket of warm water with a squirt of mild dish soap.
- Scrub gently with a soft bristle brush or sponge, working in small circles from top to bottom on both sides.
- Rinse with a garden hose on a low pressure setting.
- Shake off extra water and wipe the frame with a towel or microfiber cloth.
This matches the routine in a window manufacturer’s screen care guide, which calls for a low pressure hose, mild soap and a soft fiber brush on standard aluminum screens. The same guide warns against solvents, abrasive cleansers and razor blades, and it tells owners of one very fine mesh screen not to use water at all. Check your own window maker’s instructions if your screens are unusually fine or came with newer premium windows.
Cleaning window screens you cannot take out
Some screens are fixed in place, and some sit in second story windows where carrying them down a ladder is a bad idea. For those, a vacuum with a brush attachment does most of the work. Run it across the outside face first, then the inside.
For grime the vacuum leaves behind, use a microfiber cloth barely dampened with soapy water, followed by a second cloth dampened with clean water. Lay a towel on the sill first, because drips run down the frame. A lint roller picks up dust and pet hair from the inside face surprisingly well, and it will not push the mesh out of shape.
Do not lean on the mesh with the heel of your hand. Screens bow easily, and a bowed screen lets insects slip in at the edges.
Screen mesh types and how much scrubbing each takes
| Mesh | How it behaves | Cleaning note |
|---|---|---|
| Fiberglass | Flexible, does not dent or rust | Stretches or tears under hard pressure, so keep the brush light |
| Aluminum | Stiffer, holds its shape | Creases and dents stay, so never grind a brush into one spot |
| Pet resistant | Thick, heavily coated weave | Takes firmer scrubbing, but rinse well since the texture holds soap |
| Solar or sun control | Dense weave that blocks some sunlight | Traps fine dust, so vacuum before washing |
To tell the two meshes apart, press lightly near the frame with one finger. Fiberglass gives and springs back, while aluminum feels stiffer and usually has a metallic sheen.
Drying window screens and putting them back
Lean each screen at an angle against a wall or fence, ideally in the sun, and let it air dry. A wet screen put back too soon traps moisture against the window track, where it collects dirt and can encourage mildew. Give the empty tracks a quick clean while the screens dry, since this is the easiest time to reach them.
Reinstall in reverse order, using your tape labels. Many homes do well with a full wash once or twice a year, often in spring when windows open for the season and again in fall. Homes near a busy road, a beach or a dusty field may need it more often. Washing the glass itself is a separate chore, covered in our guide to cleaning windows.
Frequently asked questions
Can I use vinegar to clean window screens?
Diluted white vinegar in warm water is a common household choice for cutting grime and water spots, and it rinses away cleanly. Rinse thoroughly afterward and keep it off painted or unfinished wood frames. Avoid solvents and abrasive cleansers, which window makers warn can damage screens.
Can I pressure wash window screens?
It is not a good idea. A pressure washer can stretch fiberglass mesh, dent aluminum and pull the spline out of the frame channel. A garden hose on a gentle setting gives enough force to rinse away soap and dirt without deforming the screen or loosening its edges.
How do I clean screens on a second story window?
If the screens come out from inside, remove them there and carry them down to wash. If they are fixed or hard to reach, vacuum them in place with a brush attachment and wipe with a barely damp microfiber cloth instead of climbing a ladder with a bucket.
How do I replace a window screen?
Replace just the mesh if the frame is sound. Pry the old spline out with a screwdriver, lay new screen over the frame so it overhangs, and roll fresh spline into the channel with a spline tool, keeping the mesh snug but not so tight that the frame bends. Trim the excess with a utility knife.
How do I repair a damaged window screen?
For a small hole, use a self-adhesive screen patch in the type that matches your mesh, aluminum or fiberglass. Press the patch over the hole and smooth it down by hand so it sticks. A larger tear calls for rescreening the whole frame with new mesh and spline.
