Hello. I found a dehumidifier. I'd like to run it but it's extremely dirty, there's a thick layer of brown tobacco on the radiator. The coils in front block access, and the fins are extremely fragile, so I don't know how to clean it. I'm afraid pressurized water could bend the fins, even from simple hose nozzles. I found something called "coil cleaner" online. Would that work in my case? Picture: https://i.ibb.co/MBMpY44/DSC00018.jpg
