Removing dried cement from floor tiles can be challenging, as cement is a tough and stubborn substance. Here are some methods you can try:
Scrape off the excess: Use a plastic putty knife or a plastic scraper to gently scrape off as much dried cement as possible without scratching the tiles. Be careful not to apply excessive force that could damage the tiles.
Vinegar solution: Create a solution of equal parts white vinegar and warm water. Soak a clean cloth in the solution and lay it over the dried cement, allowing it to sit for about 15-20 minutes. The vinegar helps to loosen the cement. Afterward, use the cloth or a soft brush to scrub the area gently. Rinse with clean water and dry the tiles.
Lemon juice: Squeeze fresh lemon juice onto the dried cement and let it sit for a few minutes. The acidity of the lemon juice can help break down the cement. Use a cloth or soft brush to scrub the area, and then rinse with clean water.
Commercial cement removers: There are specialized cement removers available in hardware stores. Follow the instructions provided on the product carefully, as different brands may have specific usage guidelines. Remember to test the product on a small, inconspicuous area of the tile first to ensure it doesn't cause any damage or discoloration.
Steam cleaning: If you have access to a steam cleaner, it can be effective in softening and loosening dried cement. Direct the steam at the affected area and use a plastic scraper or cloth to gently remove the softened cement. Be cautious not to expose the tiles to excessive heat for an extended period, as it could potentially damage certain types of tiles.
Professional assistance: If the above methods don't work or you're concerned about damaging the tiles, it may be best to seek professional help. Professional tile and grout cleaners have experience and specialized tools to safely remove dried cement without causing harm to the tiles.
Remember to always wear protective gloves and goggles when working with any chemical solutions or cement removers. Additionally, ventilate the area properly to avoid inhaling any strong fumes.
