do you flush before squirting toilet cleaner around the bowl? sad i know, but whilst sat on the loo this morning i read the bottle of my harpic and it says that 7/10 people flush the loo before squirting around the rim which wastes a lot of water over the course of the year. never really thought of it before and i have to admit i do flush before squirting cleaner down the loo but don't really know why i8 do. anyone else do this?
