How do you clean grout?
The grout in my bathroom floor needed a good scrubbing. A woman at walmart told me about how she cleaned grout. She use to have a housekeeping service. She said use Lysol toilet bowl cleaner and put a bead along the grout lines. Then take a brush mop and brush it. Mop it clean and the grout will be like new. If very stained, then leave the cleaner on for a few minutes. I tried it and it works great! I did my shower walls too. Only thing I don't care the smell of the Lysol toilet cleaner, it's weird. But doesn't linger.
