How to Clean and Repair Window Screens
Remove each screen, lay it flat on a soft surface, vacuum both sides with a brush attachment, wash with soapy water and a soft brush, rinse with a hose, inspect for tears or holes, and patch small damage with a screen repair kit. Reinstall after the screens are fully dry.

The steps
- 1
Remove screens from windows
Most screens pop out from the inside by pulling tabs or pushing spring clips. Lift the screen up into the top channel, then swing the bottom out. Handle screens by the frame, not the mesh, to avoid stretching or tearing. Lean them against a wall or lay them flat.

Lay flat on a soft surface
Place each screen flat on a towel, drop cloth, or clean grass. Avoid concrete or gravel, which can snag and tear the mesh. Working flat prevents the screen from bending or bowing while you clean and inspect it.
- 3
Vacuum both sides
Use a vacuum with a brush attachment on low suction to remove dust, pollen, cobwebs, and loose debris from both sides of the screen. This dry pass removes the bulk of the buildup so your wash water stays cleaner and you can see the mesh clearly for inspection.

Wash with soapy water and a soft brush
Mix a few drops of dish soap in a bucket of warm water. Dip a soft brush or sponge and gently scrub both sides of the mesh. Work in straight lines rather than circles to avoid distorting the weave. Scrub the frame too, especially the bottom rail where dirt collects.
- 5
Rinse with a garden hose
Rinse each screen with a gentle stream from a garden hose. Hold the hose at an angle so water flows across the screen rather than pushing through it at high pressure. High pressure can push the mesh out of the frame channel. Rinse until the water runs clear.

Inspect for tears and holes
Hold each clean screen up to the light. Even small holes are visible when backlit. Check the corners where the mesh meets the frame, the bottom rail where pets and furniture cause damage, and any area that looks stretched or distorted. Mark damage with a small piece of tape.

Patch small tears with a repair kit
For holes smaller than about 2 inches, use a peel-and-stick screen patch or a spline patch from a repair kit. Cut the patch at least 1 inch larger than the hole on all sides. Press it firmly over the damage. For larger tears or stretched mesh, the screen needs to be rescreened entirely.

Reinstall after drying
Let screens dry completely before reinstalling. Wet screens drip onto sills and can cause water stains. Slide the screen top into the upper channel first, then push the bottom into the lower channel until it clicks into the spring clips or friction tabs.
Why screen maintenance matters
Window screens do two simple jobs: let air in and keep bugs out. A clean screen does both well. A dirty screen restricts airflow, blocks natural light, and looks grimy from inside and out.
Beyond appearance, screen maintenance extends the life of the screens themselves. Dust, pollen, and pollution build up on the mesh and frame over time. This buildup traps moisture against the frame, causing aluminum frames to oxidize and wooden frames to rot. A 10-minute wash twice a year keeps screens functioning for 15 to 20 years instead of 8 to 10.
Damaged screens defeat their purpose entirely. A single small hole lets mosquitoes, flies, and gnats into your home. Screen mesh also keeps out larger pests like wasps, stink bugs, and spiders. Patching holes immediately after you find them saves you from dealing with insects indoors all season.
Cleaning technique
The two-step method of vacuuming first and washing second gives the best results with the least effort.
Vacuuming removes the loose layer of dust, pollen, pet hair, and cobwebs. Without this step, mixing all that debris with water creates a muddy paste that smears across the mesh and is harder to remove. Use a brush attachment and low suction. High suction can pull the mesh out of the spline channel on older screens.
Washing with soapy water removes the film of pollution, cooking grease, and fine particles that vacuuming misses. Use a soft brush or sponge and gentle strokes. Aggressive scrubbing with a stiff brush can stretch fiberglass mesh or pop it out of the frame. Work in straight lines along the mesh weave.
Rinse with a gentle hose stream, not a pressure washer. Screens are held in the frame by a thin rubber spline pressed into a channel. High water pressure can push the mesh and spline right out of the frame.
Patching vs rescreening
Small holes and tears under 2 inches are worth patching. A peel-and-stick screen patch takes 30 seconds to apply and holds for years. The patch is visible up close but invisible from a few feet away. This is the fastest and cheapest fix.
Rescreening makes sense when the mesh has multiple tears, is stretched and no longer taut, or has degraded from UV exposure to the point where it tears easily. Rescreening a single window screen takes about 15 minutes. Buy new mesh, new spline, and a spline roller. Lay the new mesh over the frame, press the spline into the channel with the roller tool, and trim the excess mesh with a utility knife.
If more than a third of your screens need rescreening, consider having a hardware store do the work. Many home centers rescreen windows for $10 to $20 per screen, and they usually finish the same day.
Storage tips for winter
If you remove screens for winter, store them upright in a dry indoor space like a garage or basement. Lean them against a wall with cardboard or towels between each screen to prevent scratching. Never stack screens flat, as the weight can stretch the mesh on the bottom screens.
Label each screen with its window location using tape on the frame. Windows are rarely identical sizes, and matching screens to windows in spring is frustrating without labels. A strip of painter's tape with a room name written in marker works well and peels off cleanly.
Frequently asked questions
- How often should I clean window screens?
- Twice a year, in spring and fall. Spring cleaning removes winter grime before you start opening windows. Fall cleaning removes pollen, dust, and insect residue before you store screens for winter or close windows for heating season.
- How do I patch a small hole in a window screen?
- Use a peel-and-stick screen patch from a repair kit. Cut the patch at least 1 inch larger than the hole on all sides. Clean the area around the hole, peel the backing, and press the patch firmly onto the mesh. For fiberglass screens, you can also use a dab of clear nail polish on pinhole tears to stop them from spreading.
- When should I rescreen instead of patching?
- Rescreen when the mesh has multiple tears, is stretched and bulging, or the holes are larger than about 2 inches. Rescreening a standard window takes about 15 minutes with a screen repair kit that includes new mesh, spline, and a roller tool. It costs about $5 to $10 per screen in materials.
- Should I remove screens for winter?
- It depends on your climate and window type. Removing screens in winter lets more sunlight through the glass, which provides passive solar heating. It also protects the screens from ice and snow damage. If your screens are easy to remove and you have storage space, take them down after the fall cleaning and store them indoors.
