Windows and blinds are some of the most visibly dirty surfaces in a home, streaked glass and dusty slats show up in daylight from across the room, but they’re also among the most skipped tasks in a regular cleaning routine. Here’s how to keep them in shape yourself, and when it makes more sense to have them handled as part of a professional visit.
DIY Window Cleaning
What You’ll Need
- A microfiber cloth or squeegee
- A basic glass cleaner or a mix of water and a small amount of dish soap or vinegar
- A dry cloth for the final pass to prevent streaking
Technique
Clean on a cloudy day or out of direct sunlight if possible, sun causes cleaner to dry too fast and leaves streaks. Work top to bottom, and use a squeegee in a single continuous stroke rather than circular wiping for the cleanest finish. Always finish window tracks and sills separately, a vacuum attachment or a damp cloth wrapped around a butter knife gets into the tight channels where dust and grit collect.
DIY Blinds Cleaning
Dust Blinds Weekly
A microfiber duster or a cloth wrapped around tongs works well for slat-by-slat dusting, this alone prevents most of the buildup that eventually requires a deeper clean.
Deeper Cleaning
For horizontal blinds, close them fully, wipe down, then flip and repeat on the other side. For heavier buildup, a damp microfiber cloth with a small amount of dish soap works on most vinyl and aluminum blinds, fabric or wood blinds need a dry approach only, since moisture can warp or stain them.
Fabric Shades and Curtains
Vacuum with a brush attachment monthly. Check care labels before any washing, many fabric window treatments are dry-clean only or require professional cleaning to avoid shrinkage or color loss.
Common Mistakes
- Spraying cleaner directly onto blinds, it pools and drips rather than lifting dust, and can streak vinyl slats.
- Using abrasive scrubbers on window screens, which can stretch or tear the mesh.
- Skipping window tracks, where grit accumulates and can scratch the glass or track over time if left unaddressed.
- Washing wood blinds with water, which causes warping and finish damage.
Exterior Windows and Screens
Exterior glass takes more punishment from weather, pollen, and road grime than interior surfaces, and is often the harder half of the job since it usually means a ladder or extension pole. Rinse dirt and grit off first with a hose before wiping, scrubbing dry dirt directly on glass can cause fine scratches over time. Window screens can usually be removed and rinsed separately with a soft brush and mild soap, let them dry fully before reinstalling to avoid trapping moisture against the frame.
Best Timing for a Full Window Clean
Spring, after pollen season winds down, and fall, before leaves and debris pile up against window wells, tend to be the two most useful times of year for a full interior and exterior window pass in Northern Virginia. Cleaning right after a heavy pollen week is one of the most noticeable, highest-impact cleaning tasks homeowners tend to put off the longest.
When to Call a Pro
Interior window and blind cleaning is a reasonable DIY task for most households on a regular basis. It makes more sense to fold into a professional visit when:
- Blinds haven’t been deep-cleaned in a long time and dusting alone isn’t cutting it.
- You’re preparing for a move, sale, or big event and want the whole home handled at once rather than tackling windows separately.
- High or hard-to-reach windows make ladder work impractical or unsafe.
- You’d simply rather spend a Saturday on anything other than window tracks.
Building It Into a Regular Clean
Interior window sills, tracks, and reachable blinds are part of what’s covered in a standard cleaning visit, while a more detailed pass on blinds, tracks, and glass throughout the home fits well into a deep cleaning. Either way, keeping windows and blinds on a regular cleaning cadence, DIY or professional, means you’re never stuck with a full day of catch-up work.
