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.

The one Jewish value everyone should hold dear in the age of AI
As friends, relatives and even colleagues dive headlong into our AI future, I’ve been stuck nervously on the platform’s edge. I’m not a skeptic of technology by nature, but by experience. I’ve watched too many shiny new toys come along, promising to make society smarter or better connected, only to become superspreaders of confusion, alienation and disenfranchisement.
So when you tell me a machine can summarize any book, draw any picture or write any email, my first thought is going to be, What could possibly go wrong?
This, too, was the reaction of the Haredi rabbis who declared a communal fast over AI last month.
“If at the push of a button, I can get a hold of a d’var torah for my Shabbos meal from AI, to us, that’s a problem,” a Haredi leader told me at the time. “No, no — I want you to open the book and read it and come up with a question and come up with an answer. That’s part of what’s holy about learning Torah. It’s not just end result. It’s the process.”
Curious about their logic, I spent some time tracking down Lakewood’s gedolim to learn more. This was no straightforward task — I found it easier to get a hold of their wives than the great rabbis themselves. Even at dinner hour, these titans of Torah study were still in the beit midrash. But eventually I got through to three — thanks to my cousin Jeffrey, who knew a rav who knew a rav — and that was fortunate, because I came away with the Jewish skeleton key to our brave new world.
That key is the Jewish value of עֲמֵילוּת (ameilut), or toil. As far as Jewish values go, ameilut is an obscure one. It lacks the celebrity swagger of its better-known peers like chesed and tzedakah or the political power of tikkun olam. It was never associated with a biblical matriarch or carved into a golem’s forehead. Yet I believe it is just as crucial. Yes, toiling is a mitzvah. And in the age of AI, ameilut can be a human road map.
The word’s root appears a couple dozen times in the Hebrew Bible — unsurprisingly, it’s a recurring theme in Job — but its salience comes not from the Torah but from commentary on Leviticus 26:3, which establishes ameilut as a sacred endeavor. When God implores Israel to “walk with” the commandments, Rashi, an 11th century rabbi whose commentaries are considered authoritative, reinterpreted this to mean that God wants Jews to be ameilim b’torah — toiling in Torah study. He is reinterpreting God’s command that we walk and move forward to also mean that we should take time to stand still, turn over (and over) the same words to find new meaning and view getting stuck as a sign of progress.
For Haredim — who pronounce it ameilus — the notion that struggle can be its own reward underpins a life spent poring over sefarim in the beit midrash (and missing phone calls from the Jewish press). It follows that ChatGPT, which transforms knowledge from something developed to something consumed, is anathema to their approach. They’ve realized that making learning easy has actually made learning hard.
To be sure, the goals of the Haredi world are not exactly the same as mine. Those communities are famously insular, wary of the internet and especially cognizant of secular society’s pernicious influence. I’m basically the opposite: I love to mix it up (including with Haredi Jews) and am extremely online. A little narishkeit is good for the soul, as far as I can tell.
But I’ve found that ameilut-maxxing translates pretty well to non-religious life, too. It’s an imperative to embrace the challenge. As a notoriously limited chef, I’m now toiling in cookbooks; as a writer, I can cherish the blank page. Reframing the hard part as the good part, then, is a reminder that the toil is actually our divine right. Because ameilut is something AI can’t experience, replicate or understand. It is the very essence of what it means to be alive.

Mistrial Declared in Case of Students Charged After Stanford Anti-Israel Protests

A judge declared a mistrial on Friday in a case of five current and former Stanford University students related to the 2024 pro-Palestinian protests when demonstrators barricaded themselves inside the school president’s office.
Twelve protesters were initially charged last year with felony vandalism, according to prosecutors who said at least one suspect entered the building by breaking a window. Police arrested 13 people on June 5, 2024, in relation to the incident and the university said the building underwent “extensive” damage.
The case was tried in Santa Clara County Superior Court against five defendants charged with felony vandalism and felony conspiracy to trespass. The rest previously accepted plea deals or diversion programs.
The jury was deadlocked. It voted nine to three to convict on the felony charge of vandalism and eight to four to convict on the felony charge to trespass. Jurors failed to reach a verdict after deliberations.
The charges were among the most serious against participants in the 2024 pro-Palestinian protest movement on US colleges in which demonstrators demanded an end to Israel’s war in Gaza and Washington’s support for its ally along with a divestment of funds by their universities from companies supporting Israel.
Prosecutors in the case said the defendants engaged in unlawful property destruction.
“This case is about a group of people who destroyed someone else’s property and caused hundreds of thousands of dollars in damage. That is against the law,” Santa Clara County District Attorney Jeff Rosen said in a statement, adding he sought a new trial.
Anthony Brass, a lawyer for one of the protesters, told the New York Times his side was not defending lawlessness but “the concept of transparency and ethical investment.”
“This is a win for these young people of conscience and a win for free speech,” Brass said, adding “humanitarian activism has no place in a criminal courtroom.”
Protesters had renamed the building “Dr. Adnan’s Office” after Adnan Al-Bursh, a Palestinian doctor who died in an Israeli prison after months of detention.
Over 3,000 were arrested during the 2024 US pro-Palestinian protest movement, according to media tallies. Some students faced suspension, expulsion and degree revocation.

i24 News – Israel’s Foreign Minister Gideon Sa’ar will represent the country at the inaugural meeting of the Gaza Board of Peace in Washington on Thursday, i24NEWS learned on Saturday.
The arrangement was agreed upon following a request from Israel’s Prime Minister Benjamin Netanyahu, who will not be able to attend.
Netanyahu pushed his Washington visit forward by a week, meeting with US President Donald Trump this week to discuss the Iran situation.
A U.N. Security Council resolution, adopted in mid-November, authorized the Board of Peace and countries working with it to establish an international stabilization force in Gaza and build on the ceasefire agreed in October under a Trump plan.
Under Trump’s Gaza plan, the board was meant to supervise Gaza’s temporary governance. Trump thereafter said the board, with him as chair, would be expanded to tackle global conflicts.
