In a large container, combine water, baking soda, lemon juice, and vinegar. Stir until the baking soda is mostly dissolved.

Transfer to Spray Bottle:
Pour the mixture into a clean spray bottle for easy application.

Apply to Grout:
Spray the solution generously over grout lines on your tiles. Make sure the grout is thoroughly covered.

Let it Sit:
Allow it to sit for 1–2 minutes. The mixture will start breaking down dirt and grime.

Scrub the Grout:
Using a small brush (like a toothbrush or grout brush), scrub the grout lines to remove dirt and stains.

Rinse and Dry:
Wipe the area with a damp cloth or mop to remove residue. Let dry completely.

Tips:

For tougher stains, let the solution sit a little longer before scrubbing.

Always test a small area first to ensure it doesn’t discolor your tiles.

Repeat once a month to maintain sparkling grout.
