After spotting a 'stain' on a customer's carpet, cleaner Karen Royle set about trying to get rid of the mark, using special carpet cleaner and plenty of elbow grease to scrub at the floor. The 59-year-old, from Formby, Merseyside, thought she'd managed to get rid of the mark and carried on cleaning the rest of the house. But a little while later she was left baffled when she returned to the same spot on the landing, only to find it had reappeared.
The mum-of-four spent another five minutes trying to remove the blue stain, but was left feeling 'mortified' when the customer caught her and explained why she was making a mistake.
