An attractive tile floor finishes off a bathroom, or kitchen, but even if you’re diligent about cleaning the surface of your floor tiles, you’ll undoubtedly find residual dirt clings to the grout in between. Not only is this unsightly, it can be unhygienic too. So where should you start if you want to learn how to clean grout from floor tiles? We’ve put together this quick guide for how to clean grout on tile floors, to help you get your floors looking brand new as quickly and efficiently as possible.

Always be sure to wear protective clothing before undertaking any deep cleaning process, open a door or window to ventilate the room, and follow the instructions on the bottles of any commercial cleaners that you use. Additionally, consult the manufacturer’s maintenance guidelines for how to clean floor grout if your floor has been recently installed.

General Strategies for Cleaning Floor Grout

  • Before you start, check the type of tiles you have and the method you should use to clean them – certain chemicals should never be used to clean marble floors, for example, as this can cause damage.
  • Clean the surface of the tiles before you start cleaning the grout to make sure no extra dirt gets in the way.
  • Work methodically: from one corner of the room, treating the horizontal grout lines first; then clean the vertical grout lines to make sure you have covered every surface.
  • Rinse all treated areas with clean water.
  • Dry the floor with an old towel or dishcloth as you go to make sure no one slips on a wet floor.

Grout Cleaning Methods

Ask your friends and family how to clean grout on floor tiles and you’ll probably hear a number of different replies. Below we’ve listed some effective remedies. Be sure to use a narrow professional grout brush or an old toothbrush, where relevant, to avoid scratching or damaging the surface of the tiles.

  1. Grout Pens

These are available at supermarkets and most hardware stores. Instead of removing the dirt, a grout pen actually applies a layer of grout paint on top, covering any stains. These can also contain ingredients to combat mould and mildew.

  1. Natural remedies

A strong solution of white vinegar and water can be very effective at cleaning grout. A paste of baking soda and lemon juice (3 parts to 1) is also a good natural grout cleaner. Apply either solution directly to the grout and leave for 10-15 minutes, before scrubbing and rinsing off. Again, always test any method in a small area first, and make sure to never mix cleaning products together.

  1. Oxygen bleach or chlorine bleach

These products should be handled with care and according to the instructions on the label. They will disinfect as well as clean your grout, but may also lighten coloured grouts. Usually, you will let the solution soak in for 15-20 minutes, and then scrub and rinse off. Remember, never mix bleach with any other product.

  1. Re-grouting your floor

If you’ve tried all the above solutions and your grout floor still looks stained and dirty, a more radical approach would be to replace the grout entirely. Consult a professional grouter for more advice.

Knowing how to clean floor grout is easy with these four options to choose from. Once you’ve finished cleaning you’ll have a tile floor to be proud of!
