How to clean radiators-they are very dusty!?
If they are just dusty, I would try using the dry swifter duster. However, if it has been a while since you did it, you may need to use a wet cloth with a cleaning product to really get it clean. FYI – if it doesn’t come clean and you need to repaint it, make sure you are using a heat resistant paint specifically designed for that type of application.
