Hi, I've just bought an aerosol of Comma Air Conditioning Cleaner which claims to kill bacteria, viruses and odours in the aircon system. It looks simple enough to use but I'm just concerned about leaving the can spewing it's contents all over the leather upholstery in the car for 10 minutes whilst it does it's job. There doesn't appear to be any warnings in the instructions, other than to "wipe off any moisture that appears on the dashboard or fittings" . I'd test some on the base of one of the seats but it's a one-shot spray so once you start spraying it carries on spraying until it's empty. Has anyone used one of these (or similar) before or heard anything dodgy? Cheers!
