The Science Behind Streak-Free Windows: What Professionals Do Differently
When it comes to window cleaning, nothing beats the satisfaction of streak-free, crystal-clear glass. But achieving this pristine finish isn’t as simple as grabbing a cloth and some spray. Professional window cleaners have mastered the science behind streak-free windows, using specific techniques and tools to deliver flawless results. Here’s what they do differently and why their methods are so effective.
1. Using the Right Tools for the Job
Professionals don’t rely on standard cleaning products or paper towels to get the job done. Instead, they use high-quality tools specifically designed for window cleaning. Key items in their arsenal include:
- Squeegees: The cornerstone of any professional’s toolkit, squeegees ensure even water removal, leaving no streaks behind. The rubber blades are replaced regularly to maintain their effectiveness.
- Microfiber Cloths: Unlike traditional rags, microfiber cloths are lint-free and highly absorbent, making them perfect for detailing and edge cleaning.
- Specialized Cleaning Solutions: Professionals often use eco-friendly, ammonia-free solutions that dissolve dirt and grease without leaving residues.
- Water-Fed Poles: For high-rise or hard-to-reach windows, water-fed poles equipped with purified water systems are used to clean without streaking.
2. The Importance of Purified Water
One of the secrets to streak-free windows lies in the water itself. Tap water contains minerals, salts, and impurities that can leave behind spots and streaks when it dries. Professionals use purified water systems that remove these contaminants, ensuring a spotless finish.
Purified water also has a natural ability to dissolve dirt and grime more effectively than regular water. When combined with the right tools, it creates the perfect formula for crystal-clear windows.
3. Perfecting the Technique
The way professionals clean windows is just as important as the tools they use. Here are some techniques they employ to achieve streak-free results:
- Pre-Cleaning: Before tackling the glass, professionals remove loose dirt and debris from the surface to prevent scratches.
- Systematic Movements: Using a squeegee, they clean in overlapping strokes, starting at the top and working their way down. This ensures no spots are missed and prevents water from dripping onto already cleaned areas.
- Edge Detailing: Professionals pay special attention to the edges and corners of the glass, where streaks are most likely to form. Microfiber cloths are often used for this step.
- Drying Techniques: Any remaining water is carefully wiped away to prevent streaking. This step is crucial, especially in areas with high humidity.
4. Timing Matters
Professional window cleaners know that timing can make or break the outcome. Cleaning windows on a sunny day might seem like a good idea, but direct sunlight causes cleaning solutions to dry too quickly, leaving streaks behind. Professionals prefer overcast days or cooler parts of the day to ensure optimal results.
5. Safety First
For high-rise buildings or windows in hard-to-reach places, safety is a top priority. Professionals use specialized equipment like harnesses, ladders, and scaffolding to ensure they can clean effectively without compromising safety. This expertise allows them to tackle challenging jobs while maintaining streak-free quality.
6. Experience and Training
What truly sets professionals apart is their experience. Years of practice have honed their skills, allowing them to identify and address potential issues, like hard water stains or stubborn grime, before they become a problem. Their training ensures they can adapt to different types of glass and environments, delivering consistent results every time.

Gaza ‘Board of Peace’ to Convene at WH on Feb. 19, One Day After Trump’s Meeting with Netanyahu

i24 News – A senior official from one of the member states confirms to i24NEWS that an invitation has been received for a gathering of President Trump’s Board of Peace at the White House on February 19, just one day after the president’s planned meeting with Israeli Prime Minister Benjamin Netanyahu.
The meeting comes amid efforts to advance the implementation of the second phase of the Gaza ceasefire, following the limited reopening of the Rafah crossing, the expected announcement on the composition and mandate of the International Stabilization Force, and anticipation of a Trump declaration setting a deadline for Hamas to disarm.
In Israel officials assess that the announcement is expected very soon but has been delayed in part due to ongoing talks with the Americans over Israel’s demands for the demilitarization of the Gaza Strip. Trump reiterated on Thursday his promise that Hamas will indeed be disarmed.

If US Attacks, Iran Says It Will Strike US Bases in the Region

Iran will strike US bases in the Middle East if it is attacked by US forces that have massed in the region, its foreign minister said on Saturday, insisting that this should not be seen as an attack on the countries hosting them.
Foreign Minister Abbas Araqchi spoke to Qatari Al Jazeera TV a day after Tehran and Washington pledged to continue indirect nuclear talks following what both sides described as positive discussions on Friday in Oman.
While Araqchi said no date had yet been set for the next round of negotiations, US President Donald Trump said they could take place early next week. “We and Washington believe it should be held soon,” Araqchi said.
Trump has threatened to strike Iran after a US naval buildup in the region, demanding that it renounce uranium enrichment, a possible pathway to nuclear bombs, as well as stopping ballistic missile development and support for armed groups around the region. Tehran has long denied any intent to weaponize nuclear fuel production.
While both sides have indicated readiness to revive diplomacy over Tehran’s long-running nuclear dispute with the West, Araqchi balked at widening the talks out.
“Any dialogue requires refraining from threats and pressure. (Tehran) only discusses its nuclear issue … We do not discuss any other issue with the US,” he said.
Last June, the US bombed Iranian nuclear facilities, joining in the final stages of a 12-day Israeli bombing campaign. Tehran has since said it has halted uranium enrichment activity.
Its response at the time included a missile attack on a US base in Qatar, which maintains good relations with both Tehran and Washington.
In the event of a new US attack, Araqchi said the consequences could be similar.
“It would not be possible to attack American soil, but we will target their bases in the region,” he said.
“We will not attack neighboring countries; rather, we will target US bases stationed in them. There is a big difference between the two.”
Iran says it wants recognition of its right to enrich uranium, and that putting its missile program on the negotiating table would leave it vulnerable to Israeli attacks.

My university wants me to sign a loyalty oath — am I in America or Vichy France?
As a historian of modern France, I have rarely seen a connection between my everyday life in my adopted state of Texas and my work on my adopted specialization: the period we call Vichy France. Apart from the Texan boast that the Lone Star Republic is bigger than the French Republic, and the small town of Paris, Texas, which boasts its own Eiffel Tower, I had no reason to compare the two places where I have spent more than half of my life.
Until now.
Last week, professors and instructors at the University of Houston received an unsettling memo from the administration, which asked us to sign a statement that we teach rather than “indoctrinate” our students.
Though the administration did not define “indoctrinate,” it hardly takes a PhD in English to read between the lines. Indoctrination is precisely what our state government has already forbidden us from doing in our classes. There must not be the slightest sign in our courses and curricula of references to diversity, identity and inclusion. The catch-all word used is “ideology,” a term Governor Greg Abbott recently invoked when he warned that “Texas is targeting professors who are more focused on pushing leftist ideologies rather than preparing students to lead our nation. We must end indoctrination.”
This is not the first time in the past several months that I have been reminded of what occurred in France during the four years that it was ruled by its German occupiers and Vichy collaborators.
Very briefly, with Germany’s rapid and complete defeat of France in 1940, an authoritarian, antisemitic and collaborationist regime assumed power. Among its first acts was to purge French Jews from all the professions, including high school and university faculties, and to impose an “oath of loyalty” to the person of Marshal Philippe Pétain, the elderly but ramrod straight and clear-headed hero of World War I.
The purpose of the oath was simple and straightforward: By demanding the fealty of all state employees to the person of Pétain, it also demanded their hostility to the secular and democratic values of the French republican tradition. Nevertheless, an overwhelming majority of teachers signed the oath —even the novelist and feminist Simone de Beauvoir, who needed her salary as a lycée teacher, as did the writer Jean Guéhenno, a visceral anti-Pétainist who continued to teach at the prestigious Paris lycée Henri IV until he was fired in 1943.
Vichy’s ministers of education understood the vital importance that schools and universities played in shaping citizens. Determined to replace the revolutionary values of liberty, equality and fraternity with the reactionary goals of family, work and homeland, they sought to eliminate “godless schools” and instill a “moral order” based on submission to state and church authorities. This radical experiment, powered by a reactionary ideology, to return France to the golden age of kings, cardinals and social castes came to an inglorious end with the Allied liberation of the country and collapse of Vichy scarcely four years after it had begun.
The French Jewish historian Marc Bloch — who joined the Resistance and sacrificed his life on behalf of a very different ideology we can call humanism — always insisted on the importance of comparative history. But comparison was important not because it identified similarities but because it illuminated differences. Clearly, the situation of professors at UH is very different from that of their French peers in Vichy France. We are not risking our jobs, much less our lives, by resisting this ham-handed effort to demand our loyalty to an anti-indoctrination memo.
But the two situations are not entirely dissimilar, either. Historians of fascism like Robert Paxton remind us that such movements begin slowly, then suddenly assume terrifying proportions. This was certainly the case in interwar France, where highly polarized politics, frequent political violence and a long history of antisemitism and anti-republicanism prepared the ground for Vichy. In France, Paxton writes, this slow, then sudden transformation “changed the practice of citizenship from the enjoyment of constitutional rights and duties to participation in mass ceremonies of affirmation and conformity.”
As an historian of France, I always thought its lurch into authoritarianism was shocking, but not surprising. After all, many of the elements for this change had existed well before 1940. But as a citizen of America, I am not just shocked, but also surprised by official demands for affirmation and conformity. One day I will find the time to think hard about my naiveté. But the time is now to think about how we should respond to these demands.
