how to clean cement from windows

Your remodel went well, but you missed the cement splatter on the windows when cleaning up yesterday. It was a long day, and the fading light made it escape your eagle eye around the job site.

Unfortunately, it looks like the cement hardened on the glass overnight. Removing concrete from glass is a challenging task, even for professionals. If the cement cures and sets on the glass, you’re in for a tough time getting rid of it.

Fortunately, we have an idea to help you with your problem. Our tried-and-tested formula to remove cement splatter from glass and windows works, and we’re going to unpack it for you in this post.

Things You’ll Need for the Job:

Head down to the hardware store and purchase these products for the cleaning job.

  • The garden hose
  • Soft sponges
  • 1-gallon bucket
  • Specialized glass cleaning agent
  • Paper towel
  • Dishwashing soap
  • Spray bottle
  • Putty knife
  • Concrete removing agent
  • Soft-bristled toothbrush

Warning: Before You Start

Before you put your plan into action, it’s important to understand the following points.

Never clean the cement off the glass using abrasive sponges or steel wool. Razor blades are also not a good idea for removing the hardened cement from the glass. Using these tools may permanently scratch or etch the glass’s surface, causing the need for a replacement.

Avoid using this process in direct sunlight. The heat from the sun’s UV rays dries the cleaning agent too quickly, resulting in streaking that’s challenging to polish out. Chemical residue on the glass after cleaning may result in scratching when trying to remove it.

How Do I Remove Hardened Cement Spatter? – The DIY Method that Works

Fill your spray bottle with 2 to 3 drops of dishwashing soap and water. Spray down the window, lubricating the surface to prevent scratching. Keep spraying the soapy water to saturate the cement. The porous nature of the cement absorbs to soapy water, making it easier to remove.

After saturating the cement for a few minutes, use a plastic putty knife to scrape it from the glass.

Rinse the glass with your hose, and sponge away any remaining residue.

If there is some cement remaining on the glass, rinse the window down again using the hose. Apply your non-acidic cement remover to the window, following the manufacturer’s directions for the product. Some removal products are liquids that dilute with water; others rely on an aerosol spray for delivery.

Spray on the remover in the shade, avoiding direct sunlight that may cause the remover to dry. Leave it to soak into the cement for the time listed by the manufacturer guideline. If the cement starts to dry, moisten with your spray bottle, but don’t let it dry.

Use the plastic putty scraper to scrape away the cement, and brush stubborn spots out using a soft-bristled toothbrush.

Rinse the window with water and dry it off. Some stubborn cement deposits might require a second round of cleaning for adequate removal. After you finish, spray it with window cleaner and buff out any remaining stains or marks.
