How to Clean Grout in Tiles

Nasty grey or black spots in the shower driving you crazy? Use these simple tips to make your tiles look great again!

Grout gets dirty and unsightly – quick! The good news is it’s much easier to clean than you might imagine. Simple household products you probably already have lying around the home often do the trick and are kind to the environment too!

How to Clean Grout in Tiles?

Grout needs special attention when it comes to mildew & mould. Grout is porous and needs special treatment to keep it clean and to keep mould under control. Simply wiping down your tiles isn’t always effective because grout lines are often below the surface. Mildew can start without you knowing it is even there and make your bathroom or floors look messy when mould appears.

Not only is mould unsightly, but it can also be bad for your health. Prevention is better than cure, and luckily, there are common household products you can find in your home that get rid of stubborn mould and mildew. These proven cleaning methods can help get your tiles hygienic, and clean, and keep them looking brand new.

How to clean mould from tile grout using baking soda & white vinegar

If you’re reading this article, there’s a chance you may have already tried several different (and expensive!) cleaning solutions but to no avail. For our recommended solution you will need the following items:

  • Baking soda

  • White vinegar

  • Spray bottle

  • Scrubbing brush

  • Toothbrush

  • Small bowl


  • In a jug, mix one part water with one part vinegar

  • Pour this mixture into a spray bottle and generously spray the affected area

  • Leave the solution to work for five minutes while you grab a cup of coffee...

  • Use a scrubbing brush and toothbrush to scrub the area

  • Rinse properly with warm water

  • Once you have used the vinegar solution, mix baking soda and water in a small bowl until it becomes a paste.

  • Use a scrubbing brush and toothbrush with the paste to scrub the grout. Spray the whole area with the vinegar solution when you are done. The vinegar combined with the baking soda will create a bubbly reaction, which will get rid of soap scum, limescale and mould. Be sure to work the baking soda into the grout lines, removing all build-up.

  • Rinse the area with warm water.

How to clean floor tile grout using hydrogen peroxide

If you notice mould, stains, or mildewed grout on your floor tiles, using hydrogen peroxide can make a big difference in returning them to their former glory.

Should you find that spraying hydrogen peroxide onto the problem area isn’t doing the trick, make a paste using baking soda and hydrogen peroxide. Apply the paste to the problem areas, let it sit, scrub it with the scrubbing brush or dish scouring pad, then rinse thoroughly with warm water. You may want to test the solution on a small section first - allowing for adjustments to the solution to get the best results.

We love using baking soda as a natural cleaning solution, so much so that we have created guides on how to clean your kettle, carpet and even mould from your ceilings using the magic of bicarb!

How to clean tile grout in the shower using white vinegar

The best way to clean tile grout in your shower is to do it regularly. Spray the shower tiles using one part water and one part white vinegar before you finish showering for the best results.

Make sure that you clearly label the bottle as “shower spray”, and put it in a higher section of your shower so that it is out of reach of kids. You don’t need to spray your shower every day, but two to three times per week will help prevent the build-up of mould and limescale, thus saving you valuable time in the long run (and elbow grease!).

Why we prefer to use natural ingredients to clean tile grout

There are several reasons why we prefer using a homemade grout cleaner with natural ingredients instead of commercial, “off the shelf” products:

  • Health: Many high-street cleaning products contain harmful chemicals that can cause skin irritation, respiratory problems, and other health issues. Natural cleaning ingredients, like white vinegar and baking soda, are a suitable alternative for people with allergies or sensitive skin.

  • Kinder to the environment: Cleaning product chemicals may end up in the water supply and harm the environment. Natural cleaning ingredients are usually biodegradable. They are often just as effective too.

  • Cheaper: Many natural cleaning ingredients are more cost-effective than using “off-the-shelf” options. They can be used for multiple cleaning tasks too, meaning you don’t have to buy a product for each part of your home!

By keeping on top of your tile grout from the start both cash and elbow grease are saved – leaving you to put your feet up, kick back and catch up on Netflix! Or find time to clean the shower screen glass!

*With all cleaning solutions we recommend first testing on a small sample area to prevent any potential surface damage.
