Gee, tuff break!
I was standing in a flooring store one day when I overheard the receptionist say, "Hold on I have an installer standing right here and he can answer your question for you".
She handed me the phone and the lady asked me when was the proper time to begin cleaning her newly installed grout she had done herself. She was having some difficulty getting the grout to come off the tiles.
I asked her when she installed the grout and she told me it was about three weeks ago. She just hadn't had time to clean it up after she installed it and it was late and she was tired that night.
I'm sorry but I have little (to no) sympathy for people that do things like that.
