How to make your tile grout look like new

We have found that over time, the white grout over our bath tends to blacken, which certainly isn’t a good look. 


I definitely like to show you the good, the bad, and the ugly. And ugly that definitely is!

We have a shower over the bath, so I think that mould likes to grow due to the water hitting the tiles at the side. Cleaning, even with mould remover, doesn’t completely get rid of the discolouration, so we decided we needed to use something to brighten the grout up again.

We used Ronseal White Grout Pen, which we got from B&Q. 


First of all, I cleaned the grout and tiles and then left them to dry. 

After shaking the grout pen, you literally use it like a normal pen. It does say not to be too heavy handed because the paint will come out too fast and overflow, which I can imagine would happen, because the product does come out really easily and quickly.

If you get any of the product on the tiles, just wipe it off with a damp cloth. It does require a steady hand to keep within the lines of the grout and after leaning over the bath doing it for a very short amount of time, I had to get Dan to help me out to finish it off!

As you can see, our grout looked as good as new again. It does say to leave it to dry for 24 hours, although I left it for about 21 hours before having a shower, and I didn’t have any problems.

We have used this pen before, and we found that the grout stayed white for quite some time.

So much quicker and easier than replacing the grout!

  1. Ooooh that sounds cool! I've heard it's a good idea to have dark grout in between tiles behind the hob in the kitchen because white shows up any food that splashes onto it, which does make sense x

  2. Oh this looks great, I’m so excited that I’ve seen this, we actually noticed this has started to happen in our bathroom and in desperate need of sorting it out since we are redecorating everywhere and it all looks nice except that on the tiles! BTW I have those exact tiles haha!

    1. Haha you must have good taste 🙂 It makes such a difference! I’m so glad I found an easy way to whiten it all again.
