Cement is the foundation of any real estate property, be it residential or commercial. However, it can be a nightmare if it manages to splash on the wrong surfaces, particularly glass windows. Yet, many construction sites have this problem, given the nature of building, and the various materials used.

Toronto Window Cleaners offers post-construction window cleaning services that are specifically designed to deal with this problem. When cement gets on glass windows, it requires a professional hand and some cunning know-how to make the issue go away. Today, we’re giving you the inside scoop on how we tackle this problem, and the techniques that can be used to remove cement from glass windows altogether.



When it comes to getting cement off of windows, remember to stay away from abrasive products such as steel wool, sharp blades and certain types of sponges, as you will probably do more damage to the glass. You’ll want to avoid anything that can leave a scratch, particularly during the removal process. Though it may seem like an insurmountable task, you can, in fact, rid yourself of cement on glass windows by staying calm, and being methodical.

Rather, you’ll want to invest in something like a plastic putty knife that won’t scratch the glass. Before getting to work, fill a spray bottle with water, and mix in a few drops of dishwashing soap. Then, douse the cement repeatedly for around 5 to 10 minutes so that it soaks in. Remember, cement is porous, which means it will absorb the soapy water, and reduce the grip it has on the window. After letting it soak, you can begin carefully prying the cement away from the window with the plastic putty knife. This may take a few tries, but be patient, and keep at it. 



When attempting this technique, make sure to do so away from direct sunlight. If possible, wait for a cloudy day, or after the sun has changed positions. Since the heat and UV rays of the sun are so intense, they will act against the soapy dishwater or other cleaning agent you’ve chosen, and dry them too quickly. You’ll want to ensure that the solution soaks the cement for as long as possible, to weaken the bonds.

The same principle holds for aftercare, as well. When the cement has been removed, it will no doubt leave residue that may need to be dealt with using non-acidic cement remover. This too will dry out quickly, beyond the recommended specs for the product. The longer it sits, the more effective it will be when it comes to removing the residue.



Getting rid of cement residue on a glass window may require some persistence on your part, but it’s not impossible. You may have to go through another round or two of cleaning using the techniques above in order to get rid of it all. When in doubt, try to use a toothbrush with soft bristles to loosen some of the residue, while hosing it down with water, and apply window cleaner products to gradually clean the entire surface.
