Schools and childcare centres are tough places to keep clean. Hundreds of small hands touch the same taps, rails and desks every day. Lunch gets eaten in classrooms. Sand, mud and grass come in on every pair of shoes.
When cleaning falls short, it shows up fast. Toilets get a reputation with students. Parents notice the smell in a nappy change room at pick-up. Teachers start wiping desks themselves before class. Business managers and centre directors end up chasing contractors on top of everything else they run.
There is also the question of who is on site. Schools need to know the people cleaning their buildings are checked, inducted and the same faces each week. Turnover and unknown casuals are a real concern for principals and directors.
