Tile grout darkens quickly, especially in bathrooms from daily use and moisture. As home cleaning experts with years of hands-on experience, we've tested countless methods—here's a simple, bleach-free trick to restore it to its original bright white.
Our go-to solution: scrubbing with a toothbrush soaked in white vinegar. It's effective, natural, and safe for most surfaces. Watch how:
Contents - An old toothbrush
- White vinegar
1. Soak the toothbrush in white vinegar.
2. Spray white vinegar directly onto the grout lines.
3. Scrub vigorously along the joints with the toothbrush.

There you have it! Your grout is back to its fresh, original color. Quick, effortless, and highly effective.
No more grimy, stained lines—they look as clean as the day they were installed.
It takes elbow grease for a full bathroom, so tackle a small section daily for easier maintenance.
This method works wonders on both floor and wall grout.
White vinegar's natural acidity disinfects and sanitizes grout, dissolving dirt, stains, and odors without harsh chemicals.
The toothbrush's bristles reach into tight spaces for a thorough, professional-level clean every time.
