Struggling with moldy, discolored tile grout in your shower? High humidity often leads to black or yellow buildup that's tough to remove. As cleaning experts who've tested numerous methods, we've found this simple homemade paste using baking soda and bleach delivers reliable, professional-level results.
This two-ingredient cleaner is easy to whip up at home and restores grout to its original whiteness. Watch how:
1. In a bowl, combine 100 g of baking soda with 1 glass of bleach to form a thick paste.
2. Apply the paste directly to the darkened grout lines.
3. Let it sit for 5 to 10 minutes.
4. Scrub the grout with an old toothbrush.
5. Allow it to work for another 5 to 10 minutes.
6. Rinse thoroughly with your showerhead or a damp cloth.
Your tile grout is now clean and brilliantly white! This method works equally well on white silicone sealants and light gray cement grout in bathrooms or kitchens.
If you need baking soda, you can find some here.
Why it works: Baking soda is a natural abrasive that loosens dirt and combats fungi like mold. Bleach kills bacteria and germs while whitening surfaces effectively.
Bleach is powerful but toxic, so use it sparingly for deep-set mold. To prevent buildup, ventilate your bathroom after every use, consider a ventilation system, and wipe down grout after showers to avoid standing water.
- Wear thick gloves and keep windows open when handling bleach.
- Use old clothes to avoid bleach stains from splashes.
- Note that wet cement grout darkens temporarily; allow full drying for true results.
- Never mix bleach with white vinegar—it produces toxic fumes. See other bleach hazards to avoid here.
