The Best Way to Clean Windows: Pro Tips for a Streak-Free Shine

Cleaning windows can feel like a simple task—spray on some cleaner, wipe it down, and done, right? But if you’ve ever stood back to admire your work only to see streaks, smudges, or spots you missed, you know there’s more to it. I’ve spent years as a professional cleaner, and I can tell you that achieving spotless, streak-free windows takes more than just elbow grease. It requires the right tools, technique, and—most importantly—the best cleaning solution. Let me walk you through everything I’ve learned about cleaning windows effectively, including tips to avoid common pitfalls and how to make your own DIY cleaner.

What Is the Best Thing to Clean Windows With?

Before we dive into the specifics of cleaning solutions, let’s talk about the tools of the trade—because the best thing to clean your windows with is using the right tools. The essential tools you’ll need include a high-quality microfiber cloth, a squeegee for a streak-free finish, a bucket for mixing your solution, and a scraper or razor blade for tough spots like bird droppings or sap. These tools, when used correctly, make all the difference between average results and windows that are truly spotless.

Essential Tools You Need for Perfectly Clean Windows

• Microfiber cloths: These are an absolute game changer. They don’t leave lint behind and are excellent for wiping down windows without leaving streaks. Keep at least two on hand: one for washing and one for drying.
• Squeegee: Many people overlook this tool, but a high-quality squeegee is essential for a streak-free finish. Professional cleaners swear by them because they remove excess water and cleaner without leaving streaks.
• Bucket: You’ll need a clean bucket for mixing your cleaning solution and rinsing your tools.
• Scraper or Razor Blade: This is for those stubborn spots like bird droppings or sap. Just be gentle so you don’t scratch the glass.
• Window cleaning solution: This could be store-bought or homemade, which we’ll discuss more in-depth shortly.

Best Professional Techniques for Cleaning Windows

The pros often use a two-step process:

1. Washing the windows: Start by wetting the window with your cleaning solution. Use your squeegee or microfiber cloth to scrub away dirt and grime.
2. Drying: This is where a squeegee really shines. Wipe off excess moisture by pulling the squeegee across the window in a smooth, continuous motion. Wipe the blade between swipes to avoid transferring dirt or water back onto the window.

What Do Professional Cleaners Use in Their Water?

One common question I get is, “What do professional cleaners use in their water?” While the specific solution can vary depending on the job, the secret is often pretty simple. Professionals don’t rely solely on store-bought cleaners. Instead, they use a mixture that’s highly effective yet gentle on the glass.

What Cleaning Solution Do Professionals Use?

A standard formula includes water, dish soap, and sometimes a dash of ammonia (especially for outdoor windows with tougher grime). This combination cuts through grease and dirt without leaving a film behind. I usually use a few drops of dish soap like Dawn in a bucket of warm water, and if needed, I’ll add a tablespoon of ammonia for exterior windows that are especially dirty.

What Is the Best Homemade Cleaning Solution Without Vinegar?

A lot of DIY window cleaning recipes call for vinegar, but some people (myself included) aren’t big fans of the smell. Luckily, there are plenty of great homemade options that don’t include vinegar and still work wonders on windows.

My Favorite Vinegar-Free Window Cleaner Recipe:

• 2 cups water
• 1/4 cup rubbing alcohol (it helps the solution evaporate quickly for fewer streaks)
• A few drops of dish soap (like Dawn)

Mix these ingredients in a spray bottle and give it a good shake. Spray it on your windows and use a microfiber cloth or squeegee to wipe them down. I love this solution because it cuts through grime and dries quickly, so you’re left with a streak-free finish.

Can You Wash Windows with Dawn and Vinegar?

Another popular homemade window cleaner includes Dawn dish soap and vinegar. Yes, you can wash windows with this mixture, and it’s actually very effective!

Dawn and Vinegar Window Cleaner Recipe:

• 1 cup white vinegar
• 1 cup water
• 1 tablespoon Dawn dish soap

Mix this solution in a spray bottle and shake well. The vinegar cuts through grime, while the Dawn soap helps lift dirt and grease. Spray it onto your windows, let it sit for a minute, then scrub with a microfiber cloth. This method works great, but if you can’t stand the smell of vinegar, the rubbing alcohol solution I mentioned earlier is a good alternative.

What Should You Not Use to Clean Windows?

Let’s talk about what NOT to use on windows, as it’s just as important. Over the years, I’ve had to rescue clients’ windows from well-meaning DIYers who tried the wrong approach.

Avoid These Window Cleaning Pitfalls:

• Paper towels: They might seem like a convenient option, but they tend to leave lint and streaks behind. Microfiber cloths are a much better choice.
• Abrasive cleaners: Any cleaner that’s gritty or contains harsh chemicals can damage the glass. It may cause micro-scratches that dull the shine over time.
• Strong ammonia or bleach solutions: A little ammonia can help with exterior grime, but be careful. Using too much or mixing ammonia and bleach can create harmful fumes and even damage the window seals.

What Is the Best Way to Wash Windows Without Streaking?

Let’s get down to it: How do you clean windows without streaking? Whether you’re tackling a small bathroom window or floor-to-ceiling glass doors, these steps will help you achieve that professional, streak-free look.

Streak-Free Window Cleaning Steps:

1. Choose a mild, streak-free cleaner: Whether it’s a store-bought option or a homemade solution like the one I shared, pick a cleaner that doesn’t leave a film behind.
2. Use the right tools: A high-quality microfiber cloth or squeegee is crucial. Make sure they’re clean, or you’ll just be moving dirt around.
3. Wipe in a consistent direction: For vertical windows, use a side-to-side motion with your squeegee. For horizontal windows, go top to bottom. This prevents streaks from forming as you dry.
4. Dry your squeegee blade: After each pass, wipe the blade with a clean cloth to remove excess water and avoid streaks.
5. Don’t forget the details: After cleaning, use a dry microfiber cloth to wipe around the edges of the window and frame. Water or cleaner left behind can cause streaks and smudges.

Why Do My Windows Look Smeared After Cleaning?

A common frustration I hear is, “Why do my windows look smeared after I clean them?” I’ve been there! The most common reason for smeared windows is improper drying or using the wrong cleaner.

Avoiding Smears:

• Too much cleaner: Less is more. Too much solution can leave behind a residue that dries into streaks.
• Drying with the wrong cloth: Paper towels, as mentioned earlier, can leave lint. Stick with microfiber or a squeegee.
• Direct sunlight: Cleaning windows in the bright sun might seem like a good idea, but the heat can cause the cleaner to dry too quickly, leaving streaks.

My go-to tip is to clean windows on a cloudy day, or in the early morning or late afternoon when the sun isn’t hitting the glass directly. This gives you more time to wipe away the solution before it dries.

Final Tips for Getting Perfectly Clean, Streak-Free Windows

So, what is the best thing to clean windows with? From my years of experience, it’s a combination of the right cleaner, proper tools, and good technique. A mild solution like Dawn and water, or a vinegar-free homemade option, will do wonders. Add in a microfiber cloth or squeegee, and you’re on your way to streak-free windows that will make your whole house look brighter.

If your windows still look smeared after you clean them, don’t get discouraged. Reassess your tools and technique, and give it another shot. It takes practice, but once you’ve got the hang of it, your windows will be so clean you might forget they’re even there!
