Many people struggle to get their windows really clean. Most of the times this is due to lack of knowledge and technique and that they don’t have the right cleaning supplies to get the job done. The reason why the professional janitorial services use specific supplies is because they work.

Use Lots of Water: Use plenty of water to get rid of the dirt that accumulates on the outside of your windows. You should be a little more careful inside as you don’t want a water puddle on your floor. Water remains one of the best cleaning agents, and it is environmentally friendly.

Use Appropriate Equipment: You can use a squeegee like the professionals or you can choose one of the microfiber cloths that work fairly well. You need to use soap with a squeegee, but you can stick to plain water with the microfiber.

Clean Your Equipment: Whatever tools you use, make sure they are clean before you use them. Dirty equipment, including sponges, applicators, squeegees and cleaner will just leave dirt on your windows. You also need to rinse your equipment often when you do more than one window at a time. If you don’t you’ll be carrying the dirt over to the next window.

The Right Time of Day: Do not wash your windows in full sunlight because you might have problems with streaking caused by the temperature of the glass. Wash the windows that get morning sun in the afternoon, and wash the windows that get afternoon sun in the morning. I know this divides the job into two, but most of us have too many windows to do at one time anyway.

Squeegee Lesson 1: Move the squeegee at an angle so the water is able to run down the glass. You can cause streaking if you don’t aim the rubber this way. Watch a professional if you are able to, and you will see what I mean.

Squeegee technique 2: Always have a rag available to clean the rubber blade of the squeegee after each stroke. That will remove access water from the blade which would just leave marks on the water the next time you set it one the window.

Squeegee Tip 3: Overlapping your strokes is the most important squeegee technique. Don’t cut the strokes too close or you might miss a spot and leave a water mark on the window.

Squeegee Tip 4: Horizontal strokes work better than vertical strokes. Why is that? Because gravity makes water run down, it is easier to systematically clean the window with horizontal strokes. Just wipe the end lines of your strokes with a rag or microfiber cloth to eliminate water marks.

Microfiber: I personally prefer this technique as there is no specific technique that you have to learn. Just use plenty of water and you will get crystal clear windows again.

Secret Tip: If for some reason you can’t get your windows really clean, just rub your dry windows with dry newspaper. Not the cleanest thing to do, but it really works. Even for cars.
