Is It Possible to Really Clean Kitchen Floor Grout?

I have 1/4" sanded grout lines in a 6 yr old kitchen floor. They are really grungy. I have scrubbed and thoroughly rinsed the entire floor with detergent ammonia solution, so the tiles are really clean. I am now attacking the grout lines with Tile Gard and a brass brush. It improves the look of the grout, but still far from new looking. Anyone out there have better ideas. I would regrout if I didn't rate the task of removing the old as nearly impossible.

I'm not familiar with that produce specifically but have completed many grout jobs that went years without a good cleaning where the krud coming off the tile was black. They turned out looking like new!

The tile cleaners were nothing specific, but certainly an acid based cleaner.

Not sure it makes a diff but I always used an old tooth brush.

They also make specific grout cleaning brushes and I have to say...it was a lot easier using them. The angle and large handle really sped things up. This is the one I used. Got em on clearance at HD for $.50.

Also, the only thing I find called Tile Gard or similar is a sealer. Definitly NOT what you want to be trying to clean with.

Thanks. That brush specifically for grout lines looks pretty good. My grout wears a toothbrush out pretty quickly. I went ahead and improvised, first using a 25% solution of muriatic acid, then following with the Tile Guard cleaner (they make a cleaner as well as a sealer). I was zealot at rinsing, probably changing my rinse bucket 10 times for 50 sq ft. It came out pretty nice and the hands and knees inspection revealed cracks that will probably have to be regrouted. All told, 8-10 hours on hands and knees.
