We have dark gray tile with light gray grout in our kitchen. It looked awesome 8 years ago, but now the grout lines are stained pretty badly in high traffic areas. We have tried various methods of cleaning including: Bleach, Comet, Baking Soda, Hydrogen Peroxide, Various all purpose and tub/tile cleaners, tsp, and I'm sure I'm forgetting some. The grout still looks dingy though. I'm beginning to think we might just need to stain the grout a darker gray, but I really did like the look of the light gray. Any last ditch effort ideas to throw at it would be greatly appreciated! via /r/DIY http://ift.tt/2pz8rHq
