chlorine smell in caravan in Caravan Chat Posted July 10, 2020 11 minutes ago, Stevan said: Always difficult to identify a smell by someone else's description. It is possible that it is an ammonia smell from a leaky fridge unit (another thread is running at the moment!), this would also account for the irritated eyes and throat. Do not just put up with the irritation, it is harmful if it goes on too long. If it is ammonia from the fridge it will dissipate in time and the fridge will not work. I would have thought that if it was from the fridge the odour would be detectable at one of the two rear vents on the caravan exterior.
