Who am I?

Skip to Cleaning Small Windows Tips

My name is Jonathan. I am a window cleaner from Sydney, Australia. I have been washing windows professionally since 1997 (I started young!). I seem to be constantly busy, cleaning residential homes, strata blocks, shop front windows and other small-medium rise commercial buildings.

You can contact me on 1300 567 862 if you would like to arrange to have your windows cleaned.

I'm often asked about tips on getting a good result. "What's the secret to getting the windows looking so clean?" my clients commonly ask. So, this web page (and the next one on cleaning small windows) answers a lot of those questions - to help both householders and the professionals.

Equipment

To get off to a good start with cleaning your windows, it's important to have good quality equipment. Some of this may be a little more specialised, but you should be able to find it all at a large hardware store,Window Cleaning Bucket or a cleaning supplies shop - just type "cleaning supplies" into a search engine to find one close to you.

Here is a list of what you would find in my window cleaning bucket

How to do it

Assuming you have at least the basics of the above tools, I'll now describe how to actually use them.

  1. Fill the bucket to about half or a bit less with cold water. Hot water will make the water evaporate too quickly. Put a few squirts of detergent into the water, or as I prefer, apply the detergent directly onto the wet mop.
  2. washing glass to work up the sudsRub the wet mop (that has detergent on it) onto the window. Give it a good rub to make sure all the dirt is lifted. This is the time to scrape any stubborn marks off with the scrapper. If you need to use the scrapper, make sure to only pass the blade in the forward direction, i.e. don't scrape backwards - this could drag the dirt, cement etc across the glass causing scratches.
  3. Now get the squeegee ready. Let's assume you're right-handed. Hold the handle of the squeegee in your right hand with your thumb half way between the top and side. When you place it on the glass, you want to have it at the correct angle.
    To work this out, say the angle when the handle is touching the glass is 0 degrees, and the angle when lifting it off the glass is 90 degrees (with the rubber still on the glass). You want the angle in between those two - about 45 degrees. Try to maintain that angle for the next step.
    We also need to have the right amount of pressure on the glass. You can really only work this out with experience. Too light and you wont collect all the water, too hard and it will be difficult to move it around. using squeedgee on glassTry to keep a constant pressure the whole time.
  4. Now you are ready to clean the water off the glass with the squeegee. Start at the top left corner and snake you way down the window. Make sure to go right to the edges. With a little practise, you will be able to manage this with no water marks left in the middle of the window.
  5. It is nearly impossible to do a window without having to wipe the edges. Even the pros normally have to do this! That's where the micro-fibre cloth comes in. This is great for getting rid of those water marks anywhere on the glass. Use it dry. You can just put it in the washing machine when it's too wet or dirty. I go through one or two per house, but beginners will normally need a few more.
  6. Use the towel to wipe up any water spilt onto the window sill and the floor.
    Hint - I generally don't use micro-fiber cloths to wipe along the bottom of the window frame because this is going to dirty it very quickly. Use the towel for that area.
  7. If there are any other marks, such as little insect marks or grubby finger marks that didn't quite come off, give it a rub with a clean part of the micro-fibre cloth, or start again with the mop. That's it! Your windows will look fantastic!
  8. Now do the same on both sides to all the windows you want clean.

So there you have the inside knowledge on how to get a perfect finish to your windows. My next free tips page discusses how to approach small sized windows - French Colonial, Lead lights and Louvers.
