If you don't clean your tile grout it can become permanently stained and look unsightly! Read on for useful grout cleaning tips to safeguard your tiles.

Not sure how to clean bathroom grout? Worried that it’ll involve spending hours scrubbing away at your tiles? Don’t worry: Cleanipedia has you covered. Use the guide below to clean your grout fast – so you can get on with more enjoyable things.

Unlike the smooth steel fixtures in our bathrooms, grout is tough to clean, and vulnerable to a build up of mould, soap-scum, and mildew. Leaving bathroom grout unattended can leave you with wobbly tiles – at worst, this can result in you having to strip them off and re-grout the lot. You can stop it from reaching this stage using these grout cleaning tips.

How to Clean Dirty Grout in Five Easy Steps

This technique is fast, efficient and only requires the following products:

  • Hydrogen peroxide, or a good quality bleach product like Domestos.
  • Baking soda.
  • An old toothbrush or bristle vegetable brush.
  • A damp cloth/sponge.

Follow the instructions on the label of the peroxide or your chosen bleach to dilute it, and be extremely careful to follow any safety guidelines, as it is a very powerful cleaner.

  1. Pour some bleach or hydrogen peroxide solution on the grout lines.
  2. Using the brush, scrub your chosen cleaner up along the grout lines.
  3. Sprinkle some baking soda over the grout.
  4. Apply some elbow grease: brush along each line vigorously.
  5. Wipe the grout lines down with a damp sponge or cloth. Rinse thoroughly.

How to Clean Bathroom Grout with Vinegar and Baking Soda

It is an old fashioned cleaning trick, but using baking soda and vinegar together is a cost effective and simple way to get your bathroom grout dirt free. It is not, however, safe to use on very old grout, as it can be quite abrasive – and it will not eliminate mould.

If you’re concerned about the strength of your grout, test this cleaning solution first on a small area before application.

What you'll need:

  • Baking Soda.
  • A toothbrush.
  • Damp cloth or sponge.
  1. Mix baking soda and vinegar in a bowl until a paste-like substance is formed.
  2. Pour the solution over each grout line.
  3. Use your toothbrush to scrub this into every crevice.
  4. Allow the mixture to settle for 10 minutes.
  5. Rinse with water using a damp sponge or cloth.

Grout Cleaning Tips 

It’s essential to keep these tips in mind as you clean grout:

  • Test each cleaning solution first on a small area before application.
  • Read all product labels.
  • Take the proper safety precautions. Wear gloves and protective clothing, work in a well-ventilated area, and keep cleaning products away from children.
  • Never use two cleaning solutions at once. Combining vinegar and bleach or ammonia and bleach with in both instances create a toxic gas.

We recommend


While a mixture of baking soda and vinegar paste will help scrub grout, for tougher stains (and particularly for mould) you’ll need a stronger commercial cleaner. Try something like Domestos Bleach Spray or Cif Power & Shine Bathroom Spray for great results. When dealing with bleach, always take safety precautions – wear gloves and ensure the area is well ventilated!

Safety Warning


Use biocides safely. Always read the label and product information before use.
