How to Clean Bathroom Grout

If you don’t regularly clean grout on your tiles, they can become permanently stained and look unsightly. Read on for some great tile and grout cleaning tips.

If you’re not sure how to clean grout on floor tiles, or anywhere else in your bathroom, Cleanipedia has you covered. Use the guide below to learn all about grout cleaning so you can get the job done fast.

Unlike cleaning the smoother steel fixtures in your bathroom, cleaning grout can be tough. It’s vulnerable to mould, soap scum and mildew building up. Leaving it unattended can also lead to wobbly tiles, which may result in you needing to strip them off and re-grout the lot. You can avoid that just by following these handy tile and grout cleaning tips.

How to Clean Grout in Five Easy Steps

You only need the following product for this fast, efficient technique:

  • Hydrogen peroxide, or a great quality bleach like Domestos.
  • Baking soda.
  • An old toothbrush or bristled brush.
  • A damp cloth or sponge.

Dilute the peroxide or bleach using the instructions on the label and be extremely careful to follow the safety guidelines because it’s a very powerful cleaner.

  1. Pour your bleach or peroxide onto the grout lines.
  2. Scrub your chosen cleaner along the grout lines with a brush.
  3. Sprinkle baking soda over the grout.
  4. Scrub vigorously, applying plenty of elbow grease.
  5. Wipe down the grout lines with a damp sponge or cloth, then rinse them thoroughly.

Grout Cleaning with Vinegar and Baking Soda

Using baking soda and vinegar is a classic, cost-effective cleaning trick – and a really safe way to clean grout in your bathroom. Remember, though, it can be quite abrasive, so it’s not safe to use on very old grout, and it won’t eliminate mould. If you’re not sure about the strength of your grout, test the cleaning solution first on a small area.

You will need:

  • Baking soda.
  • A toothbrush.
  • A sponge or damp cloth.
  1. Mix the vinegar and baking soda in a bowl until they form a paste-like substance.
  2. Pour the paste over each grout line.
  3. Scrub the solution into every crevice with the toothbrush.
  4. Let the mixture settle for 10 minutes.
  5. Use the damp cloth or sponge to rinse the grout with water.

Tips for Cleaning Grout

The following tips are essential for tile and grout cleaning:

  • Always test your solution on a small area before application.
  • Read all the product labels.
  • Always take proper safety precautions, like wearing gloves and protective clothing, working in a well-ventilated area and keeping cleaning products away from children.
  • Never use more than one cleaning solution. Combining vinegar and bleach or ammonia and bleach will create a toxic gas.

We recommend


Mixing baking soda with vinegar paste can help when cleaning grout, but for tougher stains you’ll need a stronger cleaner. Try Domestos Bleach Spray or Jif Power & Shine Bathroom for better results. Follow safety precautions when cleaning grout with bleach. Wear gloves and make sure the area is ventilated.

Safety Warning


Be careful when using biocides. Always read the label and product information before use.
