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!

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.

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.

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.

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.

n expect to pay $4 to $7 per pane. When hiring a commercial window cleaner, you can expect to pay $1 to $8 for inside windows to be cleaned.

Please consider hiring a professional to eliminate the risk of injury or death from falls from ladders or other window cleaning equipment.

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 to help cut old dirt stains.

A warning against ammonia; it will ruin window tint.

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.

Ask any professional who has been cleaning windows for 10 years or longer, and they all will tell you the same answer: Use Dawn dish washing 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.

Window cleaning companies typically include the following when cleaning your windows:

  • Window panes inside & outside
  • Bug screens- Removing, cleaning & reinstalling
  • Window sills
  • Any other dust, dirt, or cob webs that are on the window frames or near the window frames.

Window cleaners typically do not include the window tracks. This is time consuming; therefore an additional charge is common.

Window cleaning prices vary across the U.S. The average cost to clean residential windows is $5 – $9 per windowpane for inside and outside. Some companies include cleaning the bug screens and tracks, but make sure to ask when getting pricing. If your home is 2 or 3 stories, then plan on spending more for higher to reach windows.

When you ask any professional window cleaner on the planet, he or she will tell you the number one tool to clean windows is a squeegee. You will get better results the more you spend on a good quality squeegee. Watch YouTube videos on how to properly use a squeegee to get streak-free results and practice!

When looking for window cleaning frequencies there are a few factors to consider.

  • Windows at your home should be cleaned a minimum of 2 times per year. Spring and fall are great markers.
  • Restaurant windows should be cleaned weekly.
  • Storefront windows or businesses with foot traffic should have their windows cleaned monthly.
  • Residential condominiums should be cleaned 3 to 4 times per year.
  • High Rise buildings should be cleaned 1 to 3 times per year depending on the type of office building and location.

Prices for commercial buildings are different than windows on your home. The typical prices for washing outside windows typically range from $1 to $4 per pane in most parts of the U.S. In larger cities where the cost of living is higher, you can expect to pay $4 to $7 per pane. When hiring a commercial window cleaner, you can expect to pay $1 to $8 for inside windows to be cleaned.

Please consider hiring a professional to eliminate the risk of injury or death from falls from ladders or other window cleaning equipment.

For the average homeowner in a house that’s about 2,000 square feet, it will take about 2 hours to wash the inside and outside windows. If you decide to clean the screens and window tracks, then plan on adding 30 more minutes.

Always remember, hiring a professional will cut the time in half, and eliminate the possibility of falling from a ladder or other injuries that window cleaning may cause.


  • Trying to clean windows on your own may result in injury or even death!
  • PLEASE consider all safety measures when cleaning windows. Ladder falls results in thousands of injuries and death each year.
  • Watch out for overhead electrical lines when using ladders or poles; there IS A RISK of electrocution.
  • If you are not confident you can do the job yourself, PLEASE hire a professional.
