I've recently applied black grout between my tiles, left them for a while and rubbed clean with a sponge but it quickly turned light grey except for a few areas where it wasn't easy to rub down with sponge ('cos of painted walls). While it looks okay, can anyone provide an explanation or a remedy? Ta.
