I've tried homemade recipes with baking soda and lemon juice. I've also tried store bought cleaner/repair stuff. So far, it's still dingy.

Anyone know of a powerful (and somewhat safe) product that can get the grout back to what it use to be so I can reseal it?

might be easier to scrape them out and just regrout. –  DA01 Jan 17 at 21:36
    
Thanks for the input. That's what I was afraid of. –  317MarkWalker Jan 19 at 19:50
    
If you haven't tried a grout saw, get one: they're only $8 at Home Depot. Then try scraping as little of the old grout out as possible. You should only have to scrape out about 1/32" to get down to clean grout. And don't try to do it all at once. Just take your time and enjoy your handiwork. –  getterdun Jan 21 at 4:32
    
I've had good success using a steam cleaner for cleaning grout. Prior to that, the only thing I'd found to work well was lots of bleach and scrubbing. –  Doresoom Jul 30 at 15:26

Mild Sulfamic acid (I've bought it at Home Depot years ago) and wear gloves.

Could you expand this a bit? Maybe include how to apply it, how to work with it, and what safety precautions need to be taken. –  Tester101 yesterday
