It's possible to clean the contacts in situ, seeing several burnt pins is fairly normal thanks to poor contact as a result of corrosion from water ingress, it doesn't mean the relay is faulty.
Replacing the plug is not a job for the faint-hearted thanks to the resin covering on the wires at the back of the plug. While it certainly isn't worth replacing the plug as preventative maintenance, unplugging the brown relay regularly to clean the pins would be a good idea, apply a healthy amount of grease to the plug on reassembly to help avoid water getting in.
