I' m baffled and looking for help! Gutted and redid kitchen just over 1 yr ago. All new cabinets and appliances. Several weeks ago, there was a stain that looked like water on kitchen floor grout where it meets the foot kick. The foot kick also was stained and somewhat warped. Thought it was water but it took too long to dry (more than one day). Stain on foot kick never went away. Now there is a second grout stain in a new place. Thought it could be the refrig but see no sign of water anywhere. The fact that the grout stain does not dry quickly makes me think it is not water. See pic. Any help appreciated!
