Over a period of time your bathroom grout can start to look a little sad. So here are a few tips to spruce up your bathroom grout:
Erase dirt between your bathroom tiles with a circular typewriter eraser. Simply roll it along the grout to rub it clean. Many of these erasers come with brushes to sweep away the eraser dust left behind.
Use an old toothbrush to scrub the mildew from the grout between your tiles or any little area where mold is growing. For more stubborn stains cover them with a paste of scouring powder that contains bleach, leave for a few hours, scrub and rinse clean with warm water. There are also many commercial products on the market that will kill mildew that contain bleach as well.
Return grout to its original, bright color by gently rubbing it with folded sandpaper. To keep your grout looking like new, apply a coat of tile sealer.
