White marks on front elevation tiles after washing are often caused by mineral deposits or efflorescence. Here's a step-by-step guide on how to remove such marks:
Identify the cause: Determine whether the white marks are due to mineral deposits or efflorescence. Efflorescence is a white, powdery substance that occurs when water evaporates and leaves behind salts on the surface of the tiles. Mineral deposits, on the other hand, can be caused by hard water or cleaning products.
Clean the tiles: Start by cleaning the tiles with a mild detergent and warm water. Use a soft brush or sponge to scrub the surface gently. Rinse the tiles thoroughly to remove any dirt or residue.
Vinegar solution: If the white marks persist, try using a vinegar solution. Mix equal parts of white vinegar and water in a bucket or spray bottle. Apply the solution to the affected areas and let it sit for a few minutes.
Scrub gently: Use a soft brush or sponge to gently scrub the white marks. Be careful not to scrub too hard, as it may damage the tiles. Continue scrubbing until the marks start to fade.
Rinse thoroughly: After scrubbing, rinse the tiles thoroughly with clean water to remove the vinegar solution. Ensure that no residue is left behind.
Efflorescence remover: If the white marks are caused by efflorescence and are stubborn to remove, you can try using a commercial efflorescence remover. Follow the instructions on the product carefully, as different brands may have different application methods.
Protect the tiles: Once the white marks are removed, it's important to protect the tiles from further staining or buildup. Consider applying a tile sealer or protective coating specifically designed for the type of tiles you have. This will help prevent future marks and make cleaning easier.
Remember to always test any cleaning solution or product in a small, inconspicuous area first to ensure it doesn't cause discoloration or damage to the tiles. Additionally, follow the manufacturer's guidelines for cleaning and maintenance of your specific type of tiles to ensure their longevity and appearance.
