Discoloured grout can affect the look and feel of your bathroom. Give the space a new lease on life by freshening your grout up with a simple cleaning routine. Regular maintenance can make a huge difference to the lifespan of your tiles, reducing the chances of needing to re-grout (a much larger and costly task!).


1Tools and materials

Here are all the tools and materials you'll need for this project.

2Wipe the surface

Using a damp cloth, wipe the tiles and grout to remove all moisture and surface dust and dirt.

3Spray on the grout cleaner

Put on the ventilation mask, eye protection and rubber gloves. Spray the grout cleaner on the affected areas and let it sit for the time specified on the pack.

4Scrub the grout

Using a scrubbing brush and a bucket of water, scrub at the grout to remove any dirt. Dip brush into the water to help the scrubbing process.

5Now for the grout pen

Shake the grout pen before use. Using the grout pen, follow the line of the grout to go over all the grout.

6What's next?

Now that the bathroom has been refreshed, turn to your kitchen with our top kitchen cleaning tips.

Health & Safety

Asbestos, lead-based paints and copper chromium arsenic (CCA) treated timber are health hazards you need to look out for when renovating older homes. These substances can easily be disturbed when renovating and exposure to them can cause a range of life-threatening diseases and conditions including cancer. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer or visit our Health & Safety page.

When following our advice in our D.I.Y. videos, make sure you use all equipment, including PPE, safely by following the manufacturer’s instructions. Check that the equipment is suitable for the task and that PPE fits properly. If you are unsure, hire an expert to do the job or talk to a Bunnings Team Member.
