I work in a PRU and will be taking a group out a couple of times a week to an outdoor activities centre using the school minibus. I have been told by the PRU that I need to clean out the minibus (quite literally to the extent of mop and bucket) after every time I take it out and ensure it is spotless. Clearely due to the nature of the activities we will be doing and despite my best efforts to try to ensure the kids keep it clean I'm sure it will not be spotless. I really don't see that it is the responsibility of the teacher driving the minibus to clean it out, and certainly not after every trip. As I'm fairly new to this and not experienced with the etiquette of looking after a school minibus I'd appreciate some advice on what happens in other schools i.e. who cleans it and how often; if at all; as the only other school I worked in with a minibus I don't remember anyone cleaning it ever!
