Tile is beautiful, durable, and generally easy to clean, but cleaning grout? That’s a different story. Because of its (typically) light coloring and porous composition, grout is prone to staining. In a tiled entry or mudroom, dirt and grime are the usual culprits, while in the kitchen; spills are more likely to blame. Soap, mold, and mildew meanwhile make it difficult to maintain clean grout in bathrooms. Fortunately, white grout is possible using only common household products and a bit of elbow grease. With any cleaning project, it’s always best to start off with the mildest cleaning solution. When in doubt about a grout cleaner, test it in a hidden spot such as the lines behind or under an appliance, for example. Do not use an all-purpose cleaner. Please do not use ammonia, as it will discolor the grout.
