Baking Soda and Vinegar

Tile is hard to keep looking new regardless of whatever you use daily to keep it that way. And white grout anywhere is a bad idea. That is something we learned very early on with a white tile bathroom floor in Milwaukee. When we moved here we didn't have a choice because the condo was already updated. Yes, we use the after shower spray and routinely clean the place but the mildew just comes back. I found a recipe that promised great results. My husband was eager to try it. Mix that baking soda and white vinegar in to a paste; apply to the affected area; use a tub brush or something like it; rinse clean... And voila! Yay, right. And we both believed it because we wanted to. I don't think it made a big difference on any of the tile we tried it in. Does anyone out there have a better solution?
