Do grout pens work

[Christian10]

Hi,

I am revamping my bathrooms and the grouting on the tiles is looking a bit stained. I have seen grout pens in B&Q ect but wondered if they actually work and for how long.

Anyone tried them?

Thanks.

Agree with #2

Might as well use a bottle of tipex !

Either some serious scrubbing with bleach etc or a grout rake and re-grout !
