It's more of a ponder.
How the Jeff does our shower get so filthy? I clean it every week, and every week the grout is orange, the tray is slimy and there are black bits round all the seals and doors.
I don't get it. Showers should be, by definition, self cleaning up to a point.
Do I live in a family of mingers? Do all showers get this grubby? And does anyone have these deep questions while cleaning?
