Discoloured tile grout

[ThundyCat]

Hi gents the tile grout in my shower has started to discolour quite badly. Is it worth me trying a grout pen or is there a specific cleaner I can buy and use.

What colour is it? Maybe worth squirting it with undiluted bleach and leave for a while...may bring off the stains.

 

[ThundyCat]

It's a yellowish colour. Apparently shampoo and showgel discolour the grout overtime.

Will give the bleach ago.

Cut it all out and re grout

Tried a good scrubbing with a nail brush and something like cif?

You can use white spirit vinegar or something like vanish oxy powder, both will whiten the grout (assuming its white).
Vinegar is ok to use on ceramic tiles but if you have natural ones like marble use the bleach powder.

Could try Blue Magic or Shadazzle, if the shopping channels are a true representation of the products either should bring them up as good as new

undiluted thick bleach on an old toothbrush + some elbow grease and it should sort it. Mine was really bad and ended up looking like new after.

 

[Yaayuh!]

Have you tried steam cleaning?
We have tiled floors downstairs as well as our bathroom and it works wonders.

Yeah the bleach seems to do the trick. I will go out and buy a firm toothbrush and give that a go.

Forget the toothbrush, I use something like one of these things:

And a strong spray cleaner.

I found a toothbrush was the perfect size to work into the grout channel. An electric toothbrush would be even better .

I tried this stuff mate

Just make sure you rinse it afterwards before you use it!

Bleach and bicarbonate of soda. Works every time. I find one of those nail brushes with the handles works best as you can apply good amount of pressure if needed.

@boxman2000 same type of brush I use - really does work well.
