Tools and materials needed for this project

1. Wash your tiles and scrub your grout

Before you get cracking, use a ‘two-step’ cleaning process. First, wash your tiles and grout with sugar soap using a toothbrush and scrubbing brush. We used Selley’s Sugar Soap concentrate for this, mixed with warm water in a bucket – it works a treat. Use your toothbrush, scrubbing brush and some elbow grease to scrub the grout and give it a good going-over.

2. Get rid of any mould

Grab your dust mask, open some windows and grab some mould killer to get in there and exterminate any mould spores – this is what’s made your grout look so dirty. Selley’s Rapid Mould Killer removes 99.9 per cent of germs and can be used in heaps of places around your house like toilets, showers and laundry surfaces. Simply spray on, leave for two to three minutes and rinse down well with water. You’ll be amazed at how effective this stuff is. But a word of warning – it’s fairly noxious, so don’t forget to wear your breather. For extra grimy tiles and grout, repeat this two-step process several times. Check out our tips on how to control mould in the long run.

3. Mask up your area

Once you’ve given everything a good clean, leave for about two hours before grabbing some masking tape and taping up around your designated tiled area. Mask up any areas you don’t want to get paint on, like around walls, taps and mirrors.

4. Use your grout pen

Grout pens are seriously handy! Simply use them like a pen to paint on a fresh layer of grout. It’s touch-dry in thirty minutes, but if you need to give them a second coat, wait one hour before re-applying.

5. Good as new

And just like that – your tiles and grout look fresh and clean.
