Hi all, Hopefully this is a simple question. The toilet in my house had been not sealed properly and was leaking (just a little bit) of water. Now after 3 months it has left the grout by the toilet looking wet - about 2" (it is a light grout). My question is, how can I fix that. Do I need to re-grout that area, or can it simply be heat dried (with a dryer)? Any help is greatly appreciated. Thanks in advance.
