Just that really. We have one toilet in work for around 6/7 women. Lately, there has been most days an obvious line of 'particles' stuck on the back section of the seat, it's a shiny white toilet seat and this is a line of something, my imagination tells me it's only possible to be a 'print' of someone's sweaty arse crack.
I wipe the seat down but it's still horrible. Could it possibly be anything else? I've racked my brains but can't think what it could be. What are the rules on signs asking people to wipe the seat down these days...bleurgh.
