I'm trying to set up a deterrent system and after a lot of thought I think I've figured out how to do this. This situation is fairly unique so I'm afraid suggestions other than the path I'm pursuing probably wouldn't apply. So I'd like to keep the discussion on the right path if at all...
I've got some 8 year old sanded bathroom floor grout that started out white but has gotten dingy over the years. It's 1" hexagon tile so it would be impossible to scrub all those lines.
What's a good brand and product for recoloring my grout back to white? It's been a while since I've looked...
