Grubby grout is one of those things that bugs us more than it should. We get it — there are bigger things in life to be concerned about. And yet… dirty grout, or the wrong colour grout, is just so damn annoying. Luckily, we’ve found two genius products that’ll change your grout colour for good.

Grout Refresh

Blogger Melissa Riker of has written about her experience using Grout Refresh, an inexpensive product you can purchase from  (yes, they ship to Australia). Riker wanted to make her white grout a dark charcoal colour, and says that the process was as easy as painting on the product and waiting.

1. Clean the area you want to re-colour and ensure it’s dry.

2. Apply the Grout Refresh using a small craft brush or a cotton swab. Don’t worry too much about painting outside the lines.

4. Spray the area with water and wipe the excess off.

5. Stand back and enjoy your new grout colour.
