Mike from Athens,
You’ll find gel bleach alongside all of the other household cleaners at any grocery store.  Clorox makes one.  I’m sure there are other brands.  The nice thing about the gel is that it stays where you put it.  We usually leave it on the grout lines for an hour or more and then rub it off.  It won’t solve all staining problems but it helps.

aye,

We used Traffic Master Stainproof grout with Scotchguard, and Tile Perfect Stand ‘n Seal sealant for what it is worth. Only been a year or so, but looks great still. I spill coffee and beer alot on the bar, sometimes at the same time, go figure.
