What do professional window cleaners use?

Professional window cleaners use two very important tools when washing windows. Weather it’s for your home or business, professionals use dish soap in water, and a squeegee to leave a streak free shiny window or mirror.

There is no need for ammonia or vinegar to get a window or mirror spot free. Simply use a good quality squeegee and you will get the results you are looking for!

How do you professionally clean windows?

Professionals clean windows with several vital tools designed for their trade. A squeegee and a window-washing mop are vital to wetting and cleaning the glass. A ladder and a pole are important for reaching higher windows to clean.

Do not use sprays, rags, newspaper or towels to clean windows; instead, use a squeegee to evenly pull off all the dirt and grime to leave a streak free window.

Remember to practice safety when using ladders to avoid death or serious injury. Hiring a professional is highly recommended.

Why should I get my windows cleaned?

Getting your windows cleaned helps keep your home or business looking it’s best. Windows that are not cleaned over time will become stained and will not be able to be restored. The sun will bake the dirt, grime, and hard water spots into the glass eventually making it impossible to clean.

How much can you make as a window cleaner?

A window cleaner typically starts out earning just above minimum wage until his skills improve, but over time and if he or she learns all the skills within window cleaning they can earn anywhere from $15 to $30 per hour. High-rise window cleaners will earn more then a novice, and technicians in larger cities earn more because of cost of living is higher than in a smaller town.

What is the best window cleaning solution?

Professional window cleaners typically all use the same solution when washing windows – dish soap. It is an old wives tale that ammonia, baking soda, or vinegar is the best window cleaning solution, but what really does the trick is using plain dish soap and professional squeegee. A squeegee pulls the dirt off the glass evenly and perfectly if used properly.

Which is better for cleaning windows ammonia or vinegar?

As a professional window cleaner, ammonia and vinegar are used to achieve 2 different results. Ammonia is known for cutting dirt, while white vinegar is known for helping to remove hard water stains from glass. Use straight vinegar on hard water stains with super fine steel wool to remove water spots on glass. Use ammonia to add to your bucket of water and dish soap to help cut old dirt stains.

What is the best way to clean windows streak free?

As a professional window cleaner for 25 years, I can tell you there are only 2 ways to achieve streak free windows. The first is a good squeegee and simple dish soap. Ammonia and vinegar is old wives-tales, and no professional uses these routinely.

The second method is to use pure water. Pure water is water that has 100% of impurities removed from it and when measuring the parts per million (PPM) it is 0. It is like a spot-free rinse for your windows. You have to scrub, or agitate your window, then rinse with the water to achieve a streak free shine. This works just fine outside, but not inside your home.

How much should I pay for window cleaning?

Window cleaning prices are not standard. They vary based on size of window, and how easy or difficult it is to access the windows. Small French windows are time consuming, so plan to pay more for small individual windowpanes. Large picture windows are actually easier and faster to clean because they do not have a bug screen to remove before cleaning.

Plan to spend $4 to $10 per windowpane on getting your windows clean in your home. Always remember to practice safety with any ladders, or walking on your roof when washing your own windows. It is highly recommended to hire a professional.

What’s the best way to clean windows without smearing?

Ask any professional who has been cleaning windows for 10 years or longer, and they all will tell you the same answer: Use Dawn dishwashing liquid, and a good squeegee. You can purchase a good quality squeegee from The Home Depot.

There is no need to use secret recipes or to use rags, newspaper, or paper towels. This will only take the dirt on the glass and smear it around. This is where the streaks come from. Use a squeegee to evenly remove the solution from the glass.

Watch videos on YouTube to learn how to properly squeegee a glass panel or mirror without streaking or smearing.
