How to clean grout in 5 steps

Discover how professionals clean grout in our guide to cleaning bathroom grout, including how to clean floor tile grout and how to remove grout.

Cleaning grout is a tedious task, but it’s an important part of keeping your kitchen or bathroom looking clean and fresh. This guide will show you how to clean dirty grout yourself without damaging it, including cleaning grout on floor tiles.

How to clean dirty grout

Whether in the bathroom or kitchen, grout has plenty of opportunities to attract dirt, with its porous nature meaning. And to top it off, grout (particularly white grout) stains easily. This staining can make it hard to bring grout back to its best, but it’s possible to keep it looking bright with some elbow grease, a few household liquids, and a selection of cleaning cloths.

Here’s what you’ll need to clean your grout on your own:how to clean bathroom grout

  • Vinegar
  • Baking soda
  • Warm water
  • Grout cleaner (for really tough stains)
  • Stiff bristled brush (such as a toothbrush)
  • Spray bottle
  • Grout cleaner
  • Gloves

How to clean bathroom grout

In this step-by-step guide to cleaning grout, we’ll focus on bathroom grout as that’s most commonly in need of cleaning to remove mould. However, the technique below can equally be used to clean kitchen grout.

  1. Fill your sink with warm water.
  2. Grab your stiff-bristled brush, wet it and then rub the grout in a circular motion. Alternatively, fill your spray bottle with warm water, spray and brush in the same way.
  3. Prepare a mix of equal parts warm water and vinegar in your spray bottle. Spray it onto the grout and leave for several minutes. Then scrub with your stiff-bristled brush and rinse with warm water.
  4. If your grout is still dirty, create a baking soda paste with warm water and apply it to the grout lines. Spray on your vinegar solution and allow it to foam. Scrub with your stiff-bristled brush and rinse with warm water.
  5. For really tough grout stains and mould, you can use a purpose-made grout cleaning solution. If applying grout cleaner, always follow the manufacturer’s instructions.

If, after all of these steps, your grout is still stained or mouldy, then you may need to re-grout your tiles. You can find out more about the cost of this in our regrouting cost guide.

How to clean grout on floor tiles

how to clean grout on floor tilesCleaning grout on floor tiles can be done in the same way as wall tiles. However, when cleaning floor tile grout there are additional safety aspects to take care of, such as creating a ‘no-walk-zone’ prior to cleaning to remove the risk of someone slipping over on the wet floor.

As floor tiles are subjected to more dirt particles from shoes, pets and food/drink spillages, it may be that you need to try a commercial or industrial strength cleaning product.

Hydrogen peroxide can be used to clean particularly stubborn dirt off of floor tiles, as can chlorine bleach, however, these chemicals should never be used together and should always be used sparingly. If you choose to use these products, follow the manufacturer’s safety instructions and wear gloves, safety goggles and a respiratory mask as a minimum.

We recommend professional grout cleaning

Cleaning grout is a laborious and time-consuming job, so prepare to set aside a considerable amount of energy and hours to do the job to a satisfactory level.

When you factor in your time and equipment costs, it may be more cost-effective to get a professional in to do the job to the highest standard.
