Hi Guys
Looking to redo about 10m2 of grout (125mm white tiles).
I have tried strong bleach/toothbrush numerous times, plus white vinegar etc BUT it is still not upto 'scratch'.
I have seen the grout pens BUT also read mixed reviews on them...
Removing old grout and redoing is not an option.
Anyone advise please.
Thanks
