how to remove concrete from glass

Removing concrete from glass can be challenging because concrete can bond strongly to the surface of the glass. However, you can attempt to remove it using the following steps:

Materials you may need:

  1. Safety glasses and gloves
  2. Plastic scraper or putty knife
  3. White vinegar
  4. Warm water
  5. Bucket
  6. Soft sponge or cloth
  7. Fine steel wool (optional)
  8. Razor blade (optional)
  9. Glass cleaner


  1. Safety First:
    • Put on safety glasses and gloves to protect your eyes and hands during the removal process.
  2. Scrape Off Excess Concrete:
    • Use a plastic scraper or putty knife to gently scrape off any excess concrete from the glass. Be careful not to scratch the glass surface.
  3. Prepare a Vinegar Solution:
    • In a bucket, mix equal parts of white vinegar and warm water to create a vinegar solution. Vinegar is mildly acidic and can help dissolve the concrete.
  4. Soak a Cloth or Sponge:
    • Dip a soft sponge or cloth into the vinegar solution, ensuring it is thoroughly saturated.
  5. Apply the Vinegar Solution:
    • Place the saturated cloth or sponge onto the concrete-affected area of the glass. Allow it to sit for 15-20 minutes. This will help soften the concrete.
  6. Gently Scrub:
    • After the soaking period, use the cloth or sponge to gently scrub the glass surface. Apply light pressure to avoid scratching the glass.
  7. Rinse with Water:
    • Rinse the glass with clean, warm water to remove any remaining vinegar solution and loosened concrete particles.
  8. Repeat if Necessary:
    • Depending on the thickness and age of the concrete, you may need to repeat the vinegar solution application and scrubbing process several times.
  9. Use Fine Steel Wool (if needed):
    • If there are still stubborn concrete residues, you can try using fine steel wool. Wet the steel wool and gently rub it over the affected area, being careful not to apply excessive pressure. Rinse with water afterward.
  10. Consider a Razor Blade (if needed):
    • As a last resort, you can carefully use a razor blade at a shallow angle to scrape off any remaining concrete. Ensure the glass is wet to prevent scratching. Use a gentle, scraping motion.
  11. Clean the Glass:
    • After you’ve successfully removed the concrete, clean the glass with a glass cleaner to ensure it’s clear and free of any residues.
  12. Inspect and Polish (if needed):
    • Inspect the glass to ensure all traces of concrete are removed. If there are any remaining marks or dull spots, you may need to polish the glass with a glass polish or a commercial glass restoration product.

Always use caution when attempting to remove concrete from glass, as aggressive scraping or the use of sharp tools can damage the glass surface. If you’re uncertain or uncomfortable with the process, consider seeking professional assistance to avoid potential damage to the glass.
