Rusty radiator

There's rust appearing at the bottom of our bathroom radiator. Do we need to replace it or can we just treat the rust?

"Rust on the bottom of bathroom radiators is generally caused by humidity in the bathroom .
The rust can be treated with primer and re painted however the end result may not always be satisfactory.
My advice would be to replace the radiator, and ensure that bathroom extractor fans are working correctly."
