Removing dried white cement from tiles can be a challenging task, but there are several methods you can try. The effectiveness of each method may depend on how long the cement has been dried and the type of tiles you have. Here's a step-by-step guide to help you remove dried white cement from tiles:
1. Safety first: Before you start, ensure you are wearing appropriate safety gear such as gloves and eye protection to avoid any potential skin or eye irritation from the chemicals you'll be using.
2. Scrape off excess cement: Use a plastic or wooden scraper to gently scrape off as much dried cement as possible from the surface of the tiles. Be careful not to scratch or damage the tiles in the process.
3. Soak the area: Wet a cloth or sponge with warm water and place it over the dried cement. Allow it to sit for at least 30 minutes to soften the cement and make it easier to remove.
4. Use vinegar: White vinegar is an acidic solution that can help break down the cement. Apply some white vinegar to the affected area and let it sit for a few minutes.
5. Scrub with a brush: After soaking the area with vinegar, use a soft-bristled brush (e.g., an old toothbrush) to scrub away the loosened cement. Be gentle to avoid damaging the tiles.
6. Try lemon juice: Lemon juice contains citric acid, which can also help dissolve cement. Squeeze some fresh lemon juice onto the dried cement and let it sit for a few minutes before scrubbing with the brush.
7. Use a commercial cleaner: If the above methods don't fully remove the dried cement, you can try using a commercial cement or lime scale remover. Follow the manufacturer's instructions carefully and test the product on a small, inconspicuous area of the tiles first to ensure it won't cause any damage or discoloration.
8. Rinse thoroughly: Once the cement has been removed, thoroughly rinse the tiles with clean water to remove any leftover residue from the cleaning process.
9. Prevent future spills: To avoid future dried cement spills, protect your tiles with drop cloths or plastic sheets when working with cement.
Remember, when attempting any cleaning method, always test it on a small, hidden area first to ensure it won't cause any damage to your tiles. Additionally, be patient and gentle while cleaning to avoid causing any harm to the tile surface.
