Grout serves a noble purpose. Much like mortar, it creates a bond, fills voids, and seal joints. Bonding tiles together, grout makes floors and countertops stronger. Grout repels water and protects the edges of tiles from chipping. The color of your grout contributes to the look of your tiled surfaces.
But, grout is porous. It is susceptible to staining, can discolor, and attract mildew. When grout troubles begin, it’s time to take action.
Keep in mind that a stain is a discoloration, but not all discolorations are stains. Most common stains can be removed. Keep in mind that a true stain is always darker than the surrounding material, in this case, the grout. If the discoloration is lighter than the grout itself, it is not a stain but surface damage that cannot be removed with stain removal techniques.
If your grout is not too badly stained, here are some at-home solutions that work well in small areas. For larger areas, or for grout lines that you can't get clean, call a local stone and tile professional.
After cleaning grout, re-sealing is recommended. Watch this short video, The Advantages of Grout Color Sealing, to see the dramatic difference our color sealing services can make for your grout lines.
