Dirty grout makes a clean bathroom look grimy – but you don’t need to spend an hour on your knees to fix it.

Try this:

  1. Mix equal parts baking soda and dish soap into a paste.
  2. Apply it to the grout lines with an old toothbrush.
  3. Spray white vinegar over the paste – it will fizz and bubble, lifting the stain.
  4. Scrub briefly, then rinse with warm water.

For stubborn mildew stains, apply a small amount of hydrogen peroxide and let it sit for 10 minutes before scrubbing.

Seal your grout once a year and you’ll find it much easier to keep clean in between.
