I have just bought a home with a bathroom with light grey/beige grout that has turned dark grey in the shower area. What is the best (cheapest and most efficient) way to fix this?
I swear by a pot of grout whitener. I do my kitchen every year and its brilliant. Looks like tippex, paint it on, let it dry for a couple of hours , spray with water to soften and wipe off. It really is that simple. DIY or Wilkinsons usually have that sort of thing. xx
i use a steamer on mine comes up as new but be carefull you dont steam to close to the grouting as it can take it off, if you dont have one then try cif bathroom spray and use a brush to scrub the grouting.
