Cleaning windows might not be at the top of your to-do list in winter—but maybe it should be. Cold temperatures, snow, salt, and condensation can quickly make your windows look foggy and dirty, reducing visibility and natural light. Fortunately, with the right approach, cleaning windows in the winter is entirely possible—and even beneficial.
In this article, we’ll cover why winter window cleaning matters, practical tips to get it done safely, and how to make your own DIY windshield washer fluid to keep things crystal clear during colder months.
Why Cleaning Windows in Winter Is Worth It
Even though it’s tempting to wait until spring, washing exterior windows during the winter has real benefits:
-
Improved visibility and sunlight: Cleaner glass lets more natural light into your home or car, which can help improve mood during dark winter days.
-
Preventing long-term damage: Road salt, dirt, and grime can stick to glass and frames, potentially corroding or etching surfaces over time.
-
Safer driving: For vehicles, regularly using a clean windshield washer fluid is crucial for maintaining visibility on snowy or muddy roads.
So yes—it is worth having windows cleaned in winter, both at home and on the road.
Tip 1: Use the Right Window Cleaning Solution
Cold weather requires a different formula. If you use a regular water-based solution, it may freeze on contact.
For Your Home’s Exterior Windows:
Use a best outdoor window cleaner or exterior window cleaner spray rated for low temperatures. Many outdoor window cleaners are now formulated to resist freezing, especially when used with a hose sprayer.
You can also mix your own exterior window cleaning solution:
-
2 cups of warm water
-
½ cup white vinegar
-
1–2 drops of dish soap
Apply with a sponge or microfiber cloth and dry with a squeegee for a streak-free finish.
Tip 2: DIY Windshield Washer Fluid for Cold Weather
Standard washer fluid might freeze in winter. Instead, try making your own homemade windshield washer fluid that can withstand cold temperatures.
Easy DIY Windshield Washer Fluid Recipe:
-
1 gallon of distilled water
-
1 cup of rubbing alcohol (isopropyl, at least 70%)
-
1 tablespoon of dish soap
-
Optional: a few drops of blue food coloring (for visibility)
This mix helps keep the fluid from freezing and effectively cleans both road grime and salt. It’s a simple and safe DIY car washer fluid option.
Other variations of DIY windshield fluid include adding vinegar or ammonia, but be cautious: some ingredients can damage car paint or rubber seals over time.
Tip 3: Clean in the Warmest Part of the Day
Timing matters. Plan your cleaning for midday, when temperatures are above freezing if possible. This helps prevent your solution from freezing on the glass and gives you better results.
Avoid cleaning windows in direct sunlight, though—rapid evaporation can cause streaks.
Tip 4: Dress for the Job
This may seem obvious, but wearing water-resistant gloves and non-slip footwear can help keep you comfortable and safe while cleaning outdoor windows. Use a ladder carefully if needed, or opt for hose window cleaner tools with extendable handles to stay safely on the ground.
Tip 5: Use a Hose Spray Cleaner for Exterior Windows
Many hose spray window cleaner products are designed for outdoor winter use. These are great for washing exterior house windows from the ground, even in cold weather.
Choose a best outdoor window cleaning solution with a nozzle that connects to your hose. This helps you apply cleaner, rinse, and dry without needing buckets or ladders.
If you prefer a more natural solution, try this outdoor window cleaning solution:
-
1 gallon of warm water
-
1 cup white vinegar
-
¼ cup cornstarch (to help polish)
Spray it on, scrub gently, rinse off, and wipe with a microfiber cloth.
Tip 6: Keep Mirrors and Interior Glass Clean Too
In winter, bathroom mirrors and inside windows can fog up or get streaky. If you’re wondering how to clean a mirror without streaks, vinegar and water still work well—even in cold weather.
Try this quick mix:
-
1 cup vinegar
-
1 cup water
-
Spray and wipe with a lint-free cloth
You can also use this as a homemade window washer fluid for cleaning interior window glass.
What to Avoid When Cleaning in the Cold
-
Avoid hot water on cold glass: It can cause the glass to crack due to rapid temperature changes. Use warm—not hot—water for cleaning.
-
Don’t use alcohol directly on painted surfaces: While rubbing alcohol helps prevent freezing, it can damage paint and trim if used carelessly.
-
Skip ammonia on car windows with tint: It can damage the film.
Stick to safe glass cleaner alternatives like vinegar-based mixes or alcohol-based window cleaner with the right dilution.
Why It’s Worth the Effort
Whether you’re prepping for holiday guests or just trying to stay safe on winter roads, clean windows in winter can make a real difference.
For your car:
-
Better vision = safer driving
-
A homemade car window washer fluid saves money and adds peace of mind
For your home:
-
More light in the home
-
Prevents long-term buildup on glass and frames
-
Keeps your space looking clean and maintained
Final Thoughts
Winter doesn’t have to be a season of dirty, foggy windows. With a little preparation, the right cleaning methods, and a reliable DIY windshield washer, you can keep your views clear and your driving safe.
So whether you’re cleaning house windows outside or crafting your own homemade wiper fluid, don’t let the cold weather stop you from maintaining your windows year-round.
