What Causes Grouting to Turn Yellow?
When wall or floor tiles are installed, there are gaps between each slab. These gaps are filled with grouting. Of course, just like natural stone surfaces, it’s also important to take proper care of the grouting in between. If you notice discolouration, the following causes could be to blame. Bath and body products Soap, shampoo and similar products can cause grout to become discoloured. Shampoos that contain colouring agents can easily discolour many surfaces, including the grouting between your tiles. Wax or sealant Some products that are designed to seal the grouting between your tiles but, after several years, they lose their initial appeal. This is due to the fact that some products contain polymers that may discolour over a longer period of time. Type of grouting Some types of grouting are more prone to yellowing than others. Epoxy grout, for example, is far more prone to discolouration. Cleaning solutions
