Well, cleaning your windows yourself is not so easy anymore, especially in your workspace with electrical items and cables around causing dangerous hazards.

Fortunately, there are plenty of professional window cleaners around and products they can utilise to do the best cleaning job and leave your windows spotless and streak-free. Want to improve your work? Carry on reading for the best window cleaning tips you should know as a professional.

Window Cleaning Techniques You Have to Know

As a professional window cleaner, you want to provide the best service for your clients which means:

  • Having a great attitude
  • Cleaning windows quickly
  • Never leaving a job half-done
  • Avoiding streaky windows

To get this right for each of your clients, you’ll need to have:

  • The right chemicals to clean with
  • The right equipment to clean with
  • The right cleaning technique

Let’s look at what you need to know to do the best job as a professional window cleaner. 

1: Using the Right Chemicals

Using the right chemicals to clean your windows is a must. Using chemicals that aren’t up to the job of cleaning windows effectively will leave excess dirt on the windowpane, making them murky and hard to see through at worst, or leave streaky marks across the glass at best. 

When cleaning windows at home, many people use washing up liquid and warm water. In principle this is fine, but too much washing up liquid to water will leave soapy suds all over your windows, creating streaky marks. Similarly, going for a glass-cleaner spray to wash your windows when they’re coated in grime, isn’t usually enough to remove all the dirt and will smear it over the windows.

Instead, a great option is a standard window-cleaning chemical to mix with water to wash the windows, before spraying a glass-cleaner on the windows to get that streak-free brilliant shine your clients want.

2: Using the Right Equipment

We’ve all walked past a professional window cleaner or two using a handheld instrument with a rubber blade to scrape the excess dirty water off a window and marvelled at the ease with which they can leave the window looking brand new. That tool is known as a squeegee and is an essential tool in the arsenal of a professional window cleaner. 

But before you start throwing water at your window panes and scraping off the dirt with your squeegee and wondering why it’s not working as well as you expected, grab a mop washer to wash the dirt away from your windows first. The best mop washers are made of nylon and microfibre fabric to make it easier to scrub away the grime without scratching your window panes. This is the best tool to use on very dirty windows to make the job easier, but can also be beneficial on light dirt to make sure the windows are as clean as possible before you start removing the excess water and causing streaky marks. 

Bear in mind that you’ll also need a bucket that’s big enough to mix your cleaning products and water as well as get your mop washer in, but most buckets will do the job. 

If you want to save yourself time and make your job a lot easier, you can also invest in a Streamline telescope pole, for higher windows and harder-to-reach places. Rather than carrying your mop and bucket up a precarious ladder, extend your Streamline pole to reach the window and use the hose to wet the window while the brush scrubs away the grime. They’re really a window cleaner’s best friend!

3: Drying the Windows

When your window panes are clean, you’ll need to dry them well to stop any excess water in the frame from dripping down the windows creating marks. But you should avoid standard cloths and newspapers as they can leave fibres and marks on your newly cleaned windows. 

Microfibre cloths are the best option as they’re highly absorbent, removing the water without leaving any marks or fibres from the material stuck to the glass. 

Cleaning the Window Frame

You may disregard the window frame when cleaning windows, but making sure the window frame is clear of dust and debris is an essential first step in preventing windows from getting dirty quickly, and avoiding streaky windows. 

Wipe away any dust, flakes of old paint or cobwebs from the window frame with a dry cloth before starting to wash the windows as this makes the job significantly easier and reduces the amount of dirt in the water when the windows are being cleaned. 

If the frames are particularly dirty, then use a wet cloth, sponge or scrubber pad to wipe off the dirt, or use a specialist cleaning product for uPVC frames to effectively remove any grime or black mould that may be forming. Your window frames will then be clean and ready for you to wash the windows much more easily. 

How to Have Streak-Free Windows

Avoiding streaky marks on clean windows is usually easier said than done, especially if you’re cleaning your windows yourself rather than hiring a professional. But with the right equipment and the right technique, you should have sparkling clean windows in no time. 

The first step you should always take when cleaning your windows is to clean the window frame. Once your window frame is clean, you can start to wash the window with your cleaning solution mixed with water and a tough mop, scrubber or Streamline hose and brush combination. Then, when your windows are fully washed, use your squeegee to scrape away the excess dirty water from the window.

If you don’t use a squeegee, you’re sure to have streaky windows as the dirty water and soap will cling to the windowpane and dry there, leaving you with dirty, murky windows. People often make the mistake of trying too hard with their squeegee, moving it quickly in a zigzag pattern downwards. Very experienced window cleaners will have perfected this technique, but if you’re just starting out or cleaning your windows yourself, you’re more likely to leave some streaks across the window like this. 

Use your squeegee slowly and carefully, ensuring you don’t leave any excess water that may drip down the windows afterwards. 

Finally, dry the windowpane with a microfibre towel to remove excess liquid, before thoroughly drying the window frame. Wooden window frames can hold onto more moisture which may drip down the glass, so it’s best to dry them as thoroughly as possible to reduce the risk of any streaks later. Don’t use other cloths than microfibre, as they’ll leave a trail of tiny fibres across the glass which won’t let your clean window sparkle as it should. 

Is Getting a Professional Window Cleaner Worth It?

If you live in a bungalow, you may think it’s better to clean your windows yourself to save on costs. While you will save money, without the specialist cleaning equipment, you won’t get the dazzling clean windows that a professional window cleaner can achieve. 

What’s more, if you have upstairs windows or an office block, you can save yourself a lot of time and danger by hiring professionals. Professional window cleaners can come to you with specialist equipment to do a great job quickly and safely, so you don’t have to risk balancing up a ladder only to have smeared windows in the end.
