Reflector is plastic and does not rust or corrode.You can wash the reflector with water and soap and a sponge, if you are not happy about the visual appearence.The reflector will not operate better or worse for a little bit of dirt.You can paint it any colour you like with car paint, but it will have no effect on reflectivity.The active reflective material is a metal mesh embedded in the plastic, you can't see it.The only area that looks like it could do with attention is the mount.But that requires taking the dish apart and sand-blasting/galvanising.Major operation, and no reception while you do it <img src="https://www.satellites.co.uk/styles/default/xenforo/smilies/smile.png"  class="smilie" loading="lazy" alt=":)" title="Smile    :)" data-shortname=":)" /></blockquote>
