Use once a month to keep grout fresh and clean.
Store the dry baking soda mixture in a jar; just add vinegar before each use.
Avoid using metal brushes—they can damage tile edges.
Variations:
For mold-prone areas, add a few drops of tea tree or eucalyptus essential oil.
On colored grout, test first in a hidden corner to avoid fading.
For floor grout, let the paste sit longer (10–15 minutes) before scrubbing.
FAQ:
Does this work on old, stubborn stains?
Yes! Let the mixture sit longer (up to 20 minutes) before scrubbing for best results.
Can I use bleach instead of vinegar?
It’s not recommended—vinegar is safer and less toxic, especially in enclosed spaces.
What if I don’t have lemon juice?
Skip it—it’s optional, but it boosts whitening and adds a fresh scent.
