In a bowl, mix baking soda with a few drops of dish soap to create a thick paste.
Apply the paste directly onto the dirty grout lines.
Fill a spray bottle with white vinegar and lemon juice (optional).
Spray over the baking soda paste—let it fizz for 5 minutes.
Scrub gently with a toothbrush or grout brush.
Rinse with warm water and wipe clean.
Watch the grime dissolve and reveal a bright, white finish!
