I.White jointing agentReasons for yellowing
1、Material-related issues
Whitening grout in bathrooms can turn yellow due to poor-quality grout sealant, which is easily stained and quickly turns yellow. If this happens, you need to reapply grout or, after sanding, apply grout in a different color to effectively address the issue.
2、Corrosion by other substances
Bathrooms are typically humid environments and are used with various chemicals, such as shampoos, shower gels, and soaps. These chemicals can react with the grout used to seal the tiles, causing the grout to discolor, particularly in white grout. To address this, you can use a toothbrush to gently scrub the discolored grout with toothpaste. This can help to reduce the discoloration, but it may be difficult to restore the grout to its original white color.
3、Exposure to direct sunlight
Some individuals have observed that the grout in bathrooms only appears discolored in specific areas. This may be due to direct sunlight exposure on that particular area, or the grout being affected by acid etching on non-slip tiles, which can also cause white grout to discolor. Discolored grout requires attention. Firstly, it is important to maintain proper grout care in everyday life, preventing the accumulation of dirt and water in the grout joints, which can lead to mold growth. When installing tiles, applying a waterproof agent can better protect the grout and prevent discoloration.
Two. What to do if the grout turns yellow?
Method 1: If the grout turns yellow, use a nano sponge and nail polish remover to try cleaning it. A nano sponge is preferred because it has excellent absorption properties.
Method 2: Clean the surface with makeup remover wipes and makeup remover solution. Note that the makeup remover wipes should be cut into small strips. Ensure adequate ventilation. The makeup remover solution has a strong odor, so avoid inhaling it. Apply the saturated makeup remover wipes to the grout lines, seal with plastic wrap, and wait. once dry, remove the wipes and observe the whitening of the grout.
